#JavaScript Fetch Data

[lizclipse]

genuinely, signals & control flow & the inject function have taken angular from being a "meh it has it's uses but it's not great" UI framework to one of my favs in the space. the way you structure components now is so unbelievably different to when i started with it back at like v6 it's like an entirely new framework and honestly it's really fun to use. i'm actually looking forward to new releases since it always opens the door to new and interesting ways of doing something that's easier than before, and i actually want to make UIs with it instead of pining for something else

What Is The Difference Between Web Development & Web Design?

In today’s world, we experience the growing popularity of eCommerce businesses. Web designing and web development are two major sectors for making a difference in eCommerce businesses. But they work together for publishing a website successfully. But what’s the difference between a web designers in Dubai and a web developer?

Directly speaking, web designers design and developers code. But this is a simplified answer. Knowing these two things superficially will not clear your doubt but increase them. Let us delve deep into the concepts, roles and differentiation between web development and website design Abu Dhabi.

What Is Meant By Web Design?

A web design encompasses everything within the oeuvre of a website’s visual aesthetics and utility. This might include colour, theme, layout, scheme, the flow of information and anything related to the visual features that can impact the website user experience.

With the word web design, you can expect all the exterior decorations, including images and layout that one can view on their mobile or laptop screen. This doesn’t concern anything with the hidden mechanism beneath the attractive surface of a website. Some web design tools used by web designers in Dubai which differentiate themselves from web development are as follows:

● Graphic design

● UI designs

● Logo design

● Layout

● Topography

● UX design

● Wireframes and storyboards

● Colour palettes

And anything that can potentially escalate the website’s visual aesthetics. Creating an unparalleled yet straightforward website design Abu Dhabi can fetch you more conversion rates. It can also gift you brand loyalty which is the key to a successful eCommerce business.

What Is Meant By Web Development?

While web design concerns itself with all a website’s visual and exterior factors, web development focuses on the interior and the code. Web developers’ task is to govern all the codes that make a website work. The entire web development programme can be divided into two categories: front and back.

The front end deals with the code determining how the website will show the designs mocked by a designer. While the back end deals entirely with managing the data within the database. Along with it forwarding the data to the front end for display. Some web development tools used by a website design company in Dubai are:

● Javascript/HTML/CSS Preprocessors

● Template design for web

● GitHub and Git

● On-site search engine optimisation

● Frameworks as in Ember, ReactJS or Angular JS

● Programming languages on the server side, including PHP, Python, Java, C#

● Web development frameworks on the server side, including Ruby on Rails, Symfony, .NET

● Database management systems including MySQL, MongoDB, PostgreSQL

Web Designers vs. Web Developers- Differences

You must have become acquainted with the idea of how id web design is different from web development. Some significant points will highlight the job differentiation between web developers and designers.

Generally, Coding Is Not A Cup Of Tea For Web Designers:

Don’t ever ask any web designers in Dubai about their coding knowledge. They merely know anything about coding. All they are concerned about is escalating a website’s visual aspects, making them more eyes catchy.

For this, they might use a visual editor like photoshop to develop images or animation tools and an app prototyping tool such as InVision Studio for designing layouts for the website. And all of these don’t require any coding knowledge.

Web Developers Do Not Work On Visual Assets:

Web developers add functionality to a website with their coding skills. This includes the translation of the designer’s mockups and wireframes into code using Javascript, HTML or CSS. While visual assets are entirely created by designers, developer use codes to implement those colour schemes, fonts and layouts into the web page.

Hiring A Web Developer Is Expensive:

Web developers are more expensive to hire simply because of the demand and supply ratio. Web designers are readily available as their job is much simpler. Their job doesn’t require the learning of coding. Coding is undoubtedly a highly sought-after skill that everyone can’t entertain.

Final Thoughts:

So if you look forward to creating a website, you might become confused. This is because you don’t know whether to opt for a web designer or a developer. Well, to create a website, technically, both are required. So you need to search for a website design company that will offer both services and ensure healthy growth for your business.

if my goal with this project was just "make a website" I would just slap together some html, css, and maybe a little bit of javascript for flair and call it a day. I'd probably be done in 2-3 days tops. but instead I have to practice and make myself "employable" and that means smashing together as many languages and frameworks and technologies as possible to show employers that I'm capable of everything they want and more. so I'm developing apis in java that fetch data from a postgres database using spring boot with authentication from spring security, while coding the front end in typescript via an angular project served by nginx with https support and cloudflare protection, with all of these microservices running in their own docker containers.

basically what that means is I get to spend very little time actually programming and a whole lot of time figuring out how the hell to make all these things play nice together - and let me tell you, they do NOT fucking want to.

but on the bright side, I do actually feel like I'm learning a lot by doing this, and hopefully by the time I'm done, I'll have something really cool that I can show off

JavaScript

Introduction to JavaScript Basics

JavaScript (JS) is one of the core technologies of the web, alongside HTML and CSS. It is a powerful, lightweight, and versatile scripting language that allows developers to create interactive and dynamic content on web pages. Whether you're a beginner or someone brushing up on their knowledge, understanding the basics of JavaScript is essential for modern web development.

What is JavaScript?

JavaScript is a client-side scripting language, meaning it is primarily executed in the user's web browser without needing a server. It's also used as a server-side language through platforms like Node.js. JavaScript enables developers to implement complex features such as real-time updates, interactive forms, and animations.

Key Features of JavaScript

Interactivity: JavaScript adds life to web pages by enabling interactivity, such as buttons, forms, and animations.

Versatility: It works on almost every platform and is compatible with most modern browsers.

Asynchronous Programming: JavaScript handles tasks like fetching data from servers without reloading a web page.

Extensive Libraries and Frameworks: Frameworks like React, Angular, and Vue make it even more powerful.

JavaScript Basics You Should Know

1. Variables

Variables store data that can be used and manipulated later. In JavaScript, there are three ways to declare variables:

var (old way, avoid using in modern JS)

let (block-scoped variable)

const (constant variable that cannot be reassigned)

Example:

javascript

Copy code

let name = "John"; // can be reassigned const age = 25; // cannot be reassigned

2. Data Types

JavaScript supports several data types:

String: Text data (e.g., "Hello, World!")

Number: Numeric values (e.g., 123, 3.14)

Boolean: True or false values (true, false)

Object: Complex data (e.g., { key: "value" })

Array: List of items (e.g., [1, 2, 3])

Undefined: A variable declared but not assigned a value

Null: Intentional absence of value

Example:

javascript

Copy code

let isLoggedIn = true; // Boolean let items = ["Apple", "Banana", "Cherry"]; // Array

3. Functions

Functions are reusable blocks of code that perform a task.

Example:

javascript

Copy code

function greet(name) { return `Hello, ${name}!`; } console.log(greet("Alice")); // Output: Hello, Alice!

4. Control Structures

JavaScript supports conditions and loops to control program flow:

If-Else Statements:

javascript

Copy code

if (age > 18) { console.log("You are an adult."); } else { console.log("You are a minor."); }

Loops:

javascript

Copy code

for (let i = 0; i < 5; i++) { console.log(i); }

5. DOM Manipulation

JavaScript can interact with and modify the Document Object Model (DOM), which represents the structure of a web page.

Example:

javascript

Copy code

document.getElementById("btn").addEventListener("click", () => { alert("Button clicked!"); });

Understanding the Difference Between a Website and a Web Page: A Complete Guide

Understanding the Difference Between a Website and a Web Page: A Complete Guide

In today’s digital landscape, terms like website and web page are used interchangeably, often causing confusion among businesses and individuals seeking an online presence. However, as a business owner or a digital marketer, understanding the difference is essential for creating an impactful online strategy.

At KSoft Technologies, where we specialize in website development, digital marketing, and SEO services, we often encounter this question from clients. This guide not only simplifies the distinction between a website and a web page but also explores their technical aspects and how they align with your business goals.

What is a Website?

A website is a collection of interlinked web pages hosted under a single domain name, designed to serve a specific purpose. Think of it as a digital storefront or an online hub that provides a comprehensive experience to users. Websites can vary significantly based on their type and functionality:

Corporate Websites Ideal for businesses aiming to showcase their products, services, and achievements. For example, the KSoft Technologies website highlights our expertise in areas like SEO, app development, and web design.

E-Commerce Websites Platforms like Amazon or Shopify allow businesses to sell products directly to customers. These websites integrate payment gateways, inventory management systems, and customer service functionalities.

Portfolio Websites Focused on showcasing individual or business achievements, these websites are ideal for freelancers or creative professionals.

Landing Pages Dedicated pages within a website that focus on lead generation and conversions, often used in digital marketing campaigns.

Blogs and Forums Content-centric websites aimed at providing information, engaging with communities, or building authority in a niche.

Technical Structure of a Website

A website comprises:

Domain Name: The unique address users type in to access the site (e.g., ksofttechnologies.com).

Hosting Server: Where all the data and files of the website are stored.

Content Management System (CMS): Tools like WordPress or Joomla that allow users to create and manage content.

Backend and Frontend: The backend involves server-side scripting (e.g., PHP, Python), while the frontend includes design elements (e.g., HTML, CSS, JavaScript).

What is a Web Page?

A web page is a single document within a website, identifiable by its unique URL. For example, on ksofttechnologies.com, the “Contact Us” page or “Services” page is a web page.

Types of Web Pages

Static Pages Content remains the same unless manually updated. They’re ideal for information like company profiles or mission statements.

Dynamic Pages Content is fetched from a database and changes based on user interaction. Examples include dashboards or search results pages.

Landing Pages Specifically designed for marketing campaigns, focusing on a single product, service, or call to action.

Blog Posts Individual articles or write-ups focused on specific topics within a blog section of a website.

Technical Structure of a Web Page

Each web page includes:

URL Structure: For example, https://ksofttechnologies.com/services.

HTML Markup: Defines the structure and content of the page.

CSS and JavaScript: For styling and functionality.

Metadata: Helps search engines understand the page content.

Key Differences Between a Website and a Web Page

 Definition

Website: A collection of multiple interlinked web pages.

Web Page: A single document within a website.

Scope

Website: Broader; provides comprehensive information or services.

Web Page: Narrower; focuses on a specific topic or purpose.

 URL

Website: Main domain name (e.g., ksofttechnologies.com).

Web Page: A subset URL (e.g., /services, /about-us).

 Interactivity

Website: Enables complex user interactions.

Web Page: May have limited or single-point interactions.

 Purpose

Website: Serves as the entire digital presence.

Web Page: Addresses a specific intent or question.

How Websites and Web Pages Work Together

To draw an analogy, a website is like a library, while web pages are the individual books or chapters within it. Each web page serves a specific purpose and contributes to the overall functionality of the website.

Example from KSoft Technologies

Website Level: Visitors land on ksofttechnologies.com, where they see an overview of our services like web development, app design, and SEO consulting.

Web Page Level: When they click on "Digital Marketing," they are directed to a dedicated page detailing our strategies, success stories, and packages.

Why Understanding the Difference Matters

For businesses, distinguishing between a website and a web page is crucial for:

Better SEO Strategy Search engines like Google evaluate websites and individual web pages differently. Optimizing individual pages for keywords (e.g., “website development services”) improves rankings and traffic.

User Experience Creating well-structured websites and easy-to-navigate web pages ensures a seamless user journey.

Content Strategy Knowing the role of each web page within your website helps in creating targeted and engaging content.

robots.txt

Day 227 - Jun 19th, 12.024

Nowadays, with things like AI crawling the internet to collect training data, I think it would be good to give this tip I found/applied today to my website, and probably my future websites.

Context

If you ever adventure yourself on web development, you will probably one day probably find about web crawlers. In summary, they are bots that browses through the internet automatically, normally collecting and indexing data and the visited website's content. They are normally used by search engines, to better find and index results.

Nowadays, they are also used for AI training, and probably were being used before the AI hype. Said crawlers normally are used to retrieve the websites' contents so it can be used for AI training.

(You can see more about web crawlers on Wikipedia.)

The robots.txt File

One thing to note is that said crawlers visit sites randomly and without prior warning or notice. However, you can block a lot of these crawlers using a robots.txt file. This is a simple plaintext file that lists what paths in your website said crawlers can and cannot visit, so you can prevent parts of your website from being indexed or stored.

You can actually see any websites' robots.txt file easily, just add /robots.txt after the domain and there's it. Here is Tumblr's robots.txt file, as you can see, it is mostly to block search engine crawlers from indexing internal and non-content paths, but it also has thing like blocking the Google's Gemini (formerly Bard) crawler for training data.

Something to notice, is that the crawler has to respect the robots.txt file to the blocking to work. Unfortunately, most of them do not respect it, that's why a lot of websites such as Twitter have things like anti-bot and HTML obfuscation or blocking using JavaScript (with most crawlers do not support) to block said crawler.

(You can see more about robots.txt on Wikipedia.)

The Tip

Well, the whole post was to give context to something which I added to my website, a robots.txt file to block AI crawlers. Personally, I do not like the whole opt-out nature of data collection used by most AI companies, even though most of my content is licensed under Creative Commons licenses. Maybe one day I will change opinion, I really am questioning myself on this whole AI business that we are right now.

But, if you would also like to block AI crawlers in your website, I would suggest doing the same and use this repository which has a ready-to-go robots.txt file that blocks the currently known crawlers. It is well documented and also lists which crawlers respect or not said file. It also provides an ai.txt file, which you can also add, it is a similar format but for just AI model training, and it was created by Spawning.

In my website, I made it automatically fetch the raw version of the file, but you can just copy-paste on your static directory and you should be fine.

Again, these files are, in some sense, a polite ask, and do not actively block the crawlers. But I would say it's better than nothing and doesn't hurt to add y'know.

does anyone know if it's worth learning php? i know that backend development is often done with other things these days but i've been interested in php on account of my 2000s programming interests and like... you know... a lot of older websites are still built on php, it's not like it's defunct or unused as a language. but i'm getting mixed signals on whether it's worth funneling my energy into that or just starting with backend JS or python or something (this is a completely new programming thing for me, i have not previously worked with backend stuff. i literally just wrapped my brain more or less around javascript promises to fetch resources and i still don't have much experience with them, much less more complex requests and actually posting data to a server)

Navigating the Web's New Frontier: Core Web Vitals Optimization in 2023

The internet is a bustling ecosystem, constantly evolving and demanding adaptability from website owners and developers. In 2023, the talk of the town in the digital realm is Core Web Vitals (CWV). To stay relevant and competitive, you must understand how to improve Core Web Vitals, grasp the CWV ranking factors, and master tips to enhance the Largest Contentful Paint (LCP). In this comprehensive guide, we'll not only explore these essential concepts but also infuse a touch of humanity into the world of digital optimization.

The Rise of Core Web Vitals

What Are Core Web Vitals?

Core Web Vitals are a set of user-centric metrics that Google considers crucial for evaluating the overall user experience of a web page. They focus on aspects like page loading speed, interactivity, and visual stability, all of which directly impact how users perceive and interact with a website.

Why Do Core Web Vitals Matter?

Core Web Vitals matter for several compelling reasons:

User-Centered Web: They emphasize user experience, aligning with the user-centric approach that Google has been championing for years.

Search Rankings: Google now uses Core Web Vitals as a ranking factor, meaning that a better-performing website has a higher chance of ranking well in search results.

Improved Engagement: Faster-loading pages and smoother interactions lead to increased user engagement, lower bounce rates, and ultimately, higher conversion rates.

Improving Core Web Vitals

Now, let's dive into the practical steps to improve Core Web Vitals:

1. Optimize Largest Contentful Paint (LCP):

LCP measures the loading performance of a web page and focuses on the largest element that appears in the viewport.

Image Optimization: Compress and serve images in modern formats like WebP. Use lazy loading to prioritize the loading of images within the viewport.

Content Delivery Network (CDN): Utilize a CDN to deliver content from servers closer to the user, reducing server response times.

Reduce Server Response Times: Optimize server performance and reduce the time it takes to render the initial content.

2. Enhance First Input Delay (FID):

FID evaluates the responsiveness of a web page by measuring the delay between a user's interaction (e.g., clicking a button) and the browser's response.

Minimize JavaScript Execution: Identify and remove or defer non-essential JavaScript. Use browser caching to reduce the load on the user's device.

Prefetch and Preload: Use resource hints like prefetch and preload to ensure critical resources are fetched in advance.

Lazy-Load JavaScript: Load JavaScript components only when they are needed to avoid blocking the main thread.

3. Tackle Cumulative Layout Shift (CLS):

CLS assesses visual stability by measuring the unexpected layout shifts that can frustrate users.

Reserve Space for Ads and Embeds: Ensure that ad placeholders and embeds reserve space to prevent sudden layout shifts when they load.

Set Dimensions for Images and Media: Specify the dimensions of images and media elements in your HTML to reserve space.

Use Transition Animations Wisely: If you use animations, make sure they don't cause unexpected layout shifts.

Core Web Vitals Ranking Factors

Understanding the CWV ranking factors is key to mastering Core Web Vitals optimization:

1. Mobile Friendliness:

With mobile devices dominating web traffic, ensuring that your website is mobile-friendly is essential. Responsive design and mobile optimization are key factors for CWV.

2. Page Loading Speed:

The speed at which your page loads is crucial for LCP. Optimize your site for fast loading by minimizing server response times and leveraging browser caching.

3. HTTPS Security:

A secure website not only protects user data but also contributes positively to CWV. Ensure your website uses HTTPS.

4. Mobile Interactivity:

FID is all about how quickly your site responds to user interactions on mobile devices. Keep JavaScript lightweight and efficient.

5. Visual Stability: CLS depends on how elements on your page are laid out. Avoid elements that can cause unexpected shifts and prioritize visual stability.

The Human Element of Core Web Vitals

Amidst all the technical jargon and optimization techniques, it's crucial to remember that behind every website visit is a human being with specific needs, expectations, and emotions. Core Web Vitals optimization isn't just about pleasing search engines; it's about creating a better online experience for real people.

Imagine a user sitting in a bustling coffee shop, attempting to access your website via their smartphone. They're seeking information or a product that can make their day easier or more enjoyable. If your website loads quickly, responds instantly to their taps and clicks, and doesn't frustrate them with unexpected layout shifts, you've not only met the criteria for Core Web Vitals but also provided a positive, user-centric experience.

Core Web Vitals in Action

Let's take a look at how real-world websites can improve Core Web Vitals:

1. E-Commerce Site:

Issue: High LCP due to large product images loading slowly.

Solution: Implement lazy loading for product images and compress images without compromising quality.

2. Blogging Platform:

Issue: High FID due to excessive JavaScript loading.

Solution: Defer non-essential JavaScript, prefetch critical resources, and prioritize lazy-loading for images and videos.

3. News Website:

Issue: High CLS due to ads causing layout shifts.

Solution: Reserve space for ads, pre-load ad placeholders, and optimize ad delivery for visual stability.

Conclusion: Striking a Balance

In 2023, Core Web Vitals optimization is more than a technical necessity; it's a commitment to enhancing the online experience for your audience. By understanding how to improve Core Web Vitals, grasping the CWV ranking factors, and keeping the human element at the forefront of your efforts, you can strike a balance between pleasing search engines and satisfying real people. Remember, every second counts, every click matters, and every layout shift can make or break a user's experience. As you embark on your Core Web Vitals optimization journey, keep the user at the center of your strategy, and you'll find that success in this new digital frontier is not just achievable but also deeply rewarding

Exploring HTMX: Revolutionizing Interactive Web Development

In the fast-paced realm of web development, new technologies are constantly emerging to enhance user experiences and streamline coding processes. HTMX is one such innovation that has gained significant attention for its ability to transform the way we build interactive web applications.

What is HTMX?

HTMX, standing for HyperText Markup eXtension, is a cutting-edge library that empowers developers to create dynamic web pages with minimal effort. It achieves this by combining the principles of AJAX (Asynchronous JavaScript and XML) and HTML, allowing developers to update parts of a webpage in real-time without the need for complex JavaScript code. HTMX Offical Site https://htmx.org/  

The Power of HTMX

Seamless User Experience HTMX facilitates a seamless and fluid user experience by enabling developers to update specific portions of a webpage without triggering a full page reload. This translates to faster load times and reduced server load, enhancing overall performance. Simplified Development Workflow Gone are the days of writing extensive JavaScript code to achieve interactive features. With HTMX, developers can leverage their existing HTML skills to add dynamic behavior to their web applications. This not only streamlines the development process but also makes the codebase more maintainable and easier to understand.

SEO-Friendly One of the concerns with traditional single-page applications is their impact on SEO. HTMX addresses this by rendering content on the server side while still providing a dynamic and interactive frontend. This means search engines can easily crawl and index the content, contributing to better SEO performance.

How HTMX Works

HTMX operates by adding special attributes to HTML elements, known as HX attributes. These attributes define the behavior that should occur when a certain event takes place. For example, the hx-get attribute triggers a GET request to fetch new content from the server, while the hx-swap attribute updates the specified element with the retrieved content. This declarative approach eliminates the need for intricate JavaScript code and promotes a more intuitive development experience. Click Me

Getting Started with HTMX

- Installation: To begin, include the HTMX library in your project by referencing the HTMX CDN or installing it through a package manager. - Adding HX Attributes: Identify the elements you want to make dynamic and add the appropriate HX attributes. For instance, you can use hx-get to fetch data from the server when a button is clicked. - Defining Server-Side Logic: HTMX requires server-side endpoints to handle requests and return updated content. Set up these endpoints using your preferred server-side technology. - Enhancing Interactions: Leverage various HX attributes like hx-swap or hx-trigger to define how different parts of your page interact with the server.   Using HTMX to enhance the interactivity of your web application involves a few simple steps: - Include HTMX Library: Begin by including the HTMX library in your project. You can do this by adding the HTMX CDN link to the section of your HTML file or by installing HTMX using a package manager like npm or yarn. htmlCopy code - Add HTMX Attributes: HTMX works by adding special attributes to your HTML elements. These attributes instruct HTMX on how to handle interactions. Some common HTMX attributes include: - hx-get: Triggers a GET request to fetch content from the server. - hx-post: Triggers a POST request to send data to the server. - hx-swap: Updates the content of an element with the fetched content. - hx-target: Specifies the element to update with the fetched content. - hx-trigger: Defines the event that triggers the HTMX action (e.g., "click"). Here's an example of how you can use the hx-get attribute to fetch content from the server when a button is clicked: htmlCopy code Fetch Data - Create Server-Side Endpoints: HTMX requires server-side endpoints to handle requests and provide data. Set up these endpoints using your preferred server-side technology (e.g., Node.js, Python, PHP). These endpoints should return the desired content in response to HTMX requests. - Use Data Attributes: HTMX also supports data attributes for passing additional information to the server. You can use attributes like data-* or hx-* to send specific data to the server when an action is triggered. - Leverage HTMX Features: HTMX offers additional features like animations, history management, and more. You can explore the documentation to discover how to implement these features according to your needs. - Test and Iterate: As with any development process, it's essential to test your HTMX-enhanced interactions thoroughly. Make sure the interactions work as expected and provide a seamless user experience. Remember that HTMX aims to simplify web development by allowing you to achieve dynamic behaviors with minimal JavaScript code. It's important to familiarize yourself with the HTMX documentation to explore its full potential and capabilities. For more detailed examples and guidance, you can refer to the official HTMX documentation at https://htmx.org/docs/.

What is Async Anyway?

Explaining async/await and general concurrency concepts in programming languages.

A lot of modern languages have async/await syntax built directly into them, and the construct can be extremely useful. Examples of languages that include these concepts are JavaScript, C#, Python, and Swift, and even modern relatively low-level languages like Rust have this syntax. Even though it's usually thought of as a more advanced feature, I think it is really not that hard to use once you get the hang of it, and it is super useful and rewarding when you really understand it.

This is going to be a bit of a long and pretty technical post, but I hope it can give you some confidence to know what async/await really does when you use it, and maybe it can help you use it more effectively. Keep in mind that I will not be able to go over everything in super deep detail, and that I am going to simplify stuff, but it should give you an idea how these systems work.

I am a little curious about eventually following this up with a post looking at how these systems compare under the hood in different programming languages, so let me know if you'd be interested in that.

Big post under the cut.

Parallelism and Concurrency

Computers today can do many things at the same time. And I mean that literally: in one instant, a modern CPU can be working on multiple instructions. That's because a single CPU has multiple cores that can all execute code (mostly) independent from each other. This is called parallelism, and the way we as programmers interact with that is through threads. Most programming languages, especially "lower level" ones, have a way for programmers to create a thread that will run some part of your code. Creating a thread is telling the computer that it can, and should, run the code in your threads in parallel (although various systems such as the OS still have discretion over when and if that actually happens).

Parallelism is not quite concurrency tho. Where parallelism is about your computer literally doing multiple things at once, concurrency is about your computer doing multiple things, but not at once. With concurrency, you kind of pretend you're doing a parallelism. But in reality, stuff doesn't happen at the same time. Instead, your system (runtime) does some work on task A a bit, then on task B, then maybe again on task A, etc., but doesn't work on the two at the same time. So, in a concurrent system it might look like task A and B are progressing simultaneously from the outside, but work actually only happens in sequence.

Let's Talk About I/O

I/O stands for input/output and describes data in your program that comes from elsewhere, or that gets sent elsewhere. So for example, user input is I/O. And similarly, a web request can be I/O, whether you send it or receive it. So let's use that as an example: you send a web request to some API to fetch you the cutest bunny images and facts:

But the service is taking its sweet time to respond.

Fact: Loading bunny fact…

With how we did it here, we halt execution of the entire thread until the response comes in (at least in most languages, more on that later). In this case, we call get a blocking method because it, well, blocks the thread without actively doing useful work.

What if we could instead use the thread for other tasks instead of just sitting there, twiddling our thumbs and waiting on the server? This smells of concurrency…

Callbacks

Callbacks are a way for programmers to avoid that period of thumb twiddling. The new getWithCallback function now returns immediately, but it doesn't return a value. Instead, we have to register the code we want to run once the server responds with the function:

The function we pass to getWithCallback is called the callback, and it gets called by the client* only once the response arrives. Oh look, here it is:

Fact: A rabbit's life span is about 8 years, though sterilized rabbits (those who are spayed/neutered) can live as long as 10-12 years.

*"The client calls it" is a big simplification, there might be a lot more stuff happening here. But the important bit is that the client magically does not need to block to wait for the response.

Promises and Futures

What JavaScript calls Promises and what a lot of the other languages call Futures is essentially sugar sprinkled on callbacks - it makes our callback code a little nicer. Callbacks can commonly create a concept called "callback hell", where you have to call a function that takes a callback inside the function that takes a callback inside the function that takes a callback…

(Code modified from https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Using_promises)

To avoid this, functions now can return a Promise instead of taking a callback. Promises represent the promise that, while a concrete value might not exist right now, it will in the future. Once the value exists, we say the Promise resolves. The code above with Promises would then look like this:

It still doesn't look perfect, and there are things you can do to make it look a little nicer, but it's so much less nested. The callback in the then function will be called once the value is ready, and the callback itself can also return a Promise. The then function then returns a Promise which will get resolved once the future from the callback is resolved. Many other languages have a concept similar to JavaScript's Promise, and it's often called something like Future or Task (because it would be too easy to have consistent naming across languages).

Now keep in mind neither of those solutions above are really "concurrency" in the definition we used above. This is because the thread we call, for example, getWithCallback on still completely belongs to us. We could keep using it, and we would not get interrupted to execute the callback. Depending on the language and runtime, the callback might get executed on a different thread, or the runtime might have to wait until we are completely done with what we were doing to then use our thread to call it. The same thing goes for the callbacks in the then method of promises.

Async/Await

And async/await is just some sugar and magic fairy dust on top of Promises (or Futures or whatever). It makes our code look like it should be blocking, but in reality it isn't. Here's what our bunny image code looks like with async/await:

So here, a couple things happen. First, the Promise is created and the web request is initiated. Then, the Promise is awaited. For that, (if the Promise is not resolved at this point already,) the task first yields, meaning it tells the runtime that it is not doing any useful work at the moment, and that the thread it ran on can be used for other tasks. The runtime then makes a note of where to continue execution when that Promise resolves, and looks around for other tasks that currently need executing to put them on that thread. After a while passes, the Promise resolves, and once the runtime has some resources available for us (maybe because another task just yielded), execution on our original task is continued with the API response.

Fact: A rabbit's teeth never stop growing! Many people believe they need to chew to keep their teeth short. While they do enjoy chewing, it's the normal wear from where their top and bottom teeth meet that keeps a rabbit's teeth short.

This is more in line with the concurrency we sought out above. We can interleave other computations while our task is still running, but during times where it is not doing any useful work. (Still, because you may have multiple threads your tasks can run on and move between, it might not always be 100% technically accurate to call this system concurrent.) This is also why it is important to not block for long in async contexts: if you're hogging the thread for too long, you're stopping other tasks from progressing and throwing a lot of the benefits you gained from doing it concurrently in the bin. Most async runtimes will give you some option to run expensive or blocking code elsewhere, so that you can keep the benefits you gain from async.

So that's the explanation what async/await does, and the broad strokes of how it works. If you have any more questions regarding the topic, feel free to ask! I think it'll be fun to occasionally write a longer post on interesting things I've learned, so if you have topic suggestions, don't be afraid to tell me!

I got the bnuuy images and facts from the animality API. The licenses on the images are not super clear, but I'll assume it's okay for me to use them here with credit because it's an open API.

I lifted the definitions and some of the explanation for parallelism and concurrency from Steve Klabnik's talk on Rust's Journey to Async/Await. The talk is more technical and very focused on Rust, but it's a great talk.

I referenced the mdn web docs at various points, they're a great resource.

CDNs Explained: How Development Agencies Use Them to Improve Site Speed

When it comes to building high-performing websites, speed is more than a luxury—it’s a necessity. Faster websites improve user experience, boost search rankings, and increase conversion rates. One of the most effective tools web developers use to achieve this is a Content Delivery Network (CDN).

A skilled Web Development Company will often integrate CDNs into your site architecture to make your website faster, more reliable, and globally accessible. But what exactly is a CDN, and how does it work behind the scenes to enhance your website’s performance?

Let’s break it down.

What Is a CDN?

A Content Delivery Network (CDN) is a network of servers distributed across different geographical locations. These servers are strategically placed to deliver website content (like images, videos, JavaScript, CSS files, and even HTML pages) from a server that is closest to the user’s location.

Instead of making every user fetch content from your original web host (which might be in one part of the world), CDNs replicate and serve it from edge servers globally. The result? Reduced latency, faster page load times, and less strain on your origin server.

Why Site Speed Matters So Much

Before diving into how development teams use CDNs, it’s important to understand why speed matters:

Improved SEO: Google considers page speed as a ranking factor.

Better User Experience: Users expect pages to load in under 3 seconds.

Higher Conversions: Faster websites see lower bounce rates and higher sales.

Lower Server Costs: Offloading static assets to a CDN can reduce bandwidth consumption and hosting costs.

Slow websites frustrate users and search engines alike—making speed optimization a core responsibility of any web development project.

How Web Development Agencies Use CDNs Effectively

Professional development teams don’t just plug in a CDN—they configure and optimize it strategically based on the website’s structure, target audience, and traffic patterns. Here’s how:

1. Serving Static Content from Edge Locations

CDNs are perfect for delivering static content—things like images, videos, CSS stylesheets, fonts, and JavaScript files. Development teams configure CDNs like Cloudflare, AWS CloudFront, or Akamai to cache these assets and serve them from the nearest server to the end user.

This reduces the time it takes for content to travel across the internet, especially for international audiences.

2. Reducing Time to First Byte (TTFB)

TTFB is the time it takes for the first bit of data to reach a user’s browser after making a request. A long TTFB can drag down your site speed—even if everything else is optimized.

CDNs reduce TTFB by minimizing the distance between the user and the server. Development teams monitor this closely and use CDN logs and analytics to optimize performance over time.

3. Image and Media Optimization

CDNs often come with built-in media optimization features. Developers can enable:

Automatic image compression

Next-gen formats like WebP

Responsive resizing based on device

Instead of hosting large, unoptimized media files, the CDN handles compression and resizing on the fly—freeing up your core server and delivering content faster.

4. Handling High Traffic Volumes

When your site experiences a surge in traffic—whether from a marketing campaign, sale, or product launch—your main server can get overwhelmed.

CDNs absorb much of this traffic by handling asset delivery, freeing up your origin server to focus on dynamic requests like form submissions, shopping cart updates, or user logins.

5. Improving Global Reach

If your audience is spread across continents, you don’t want users in Asia or Europe waiting for content hosted in the U.S. A CDN ensures they access a version of your site from a local or nearby server, drastically improving loading times and consistency around the world.

6. Added Layer of Security

Many CDNs offer DDoS protection, firewall rules, and bot filtering features. Development teams configure these security layers through the CDN’s dashboard, ensuring that your site is not only fast—but also safe.

This is especially crucial for eCommerce sites, fintech platforms, or any website dealing with sensitive customer data.

Conclusion

In the modern web ecosystem, speed and performance are no longer optional—they're expected. CDNs play a critical role in meeting those expectations by delivering content faster, more securely, and with better reliability.

A professional Web Development Company knows how to implement and fine-tune CDN integration to ensure your site performs optimally across devices and geographies. From serving static content and reducing TTFB to scaling under pressure and protecting against threats, CDNs have become essential to modern web development success.

7 Essential JavaScript Features Every Developer Should Know Early.

JavaScript is the backbone of modern web development. Whether you're just starting out or already have some coding experience, mastering the core features of JavaScript early on can make a big difference in your growth as a developer. These essential features form the building blocks for writing cleaner, faster, and more efficient code.

Here are 7 JavaScript features every developer should get familiar with early in their journey:

Let & Const Before ES6, var was the only way to declare variables. Now, let and const offer better ways to manage variable scope and immutability.

let allows you to declare block-scoped variables.

const is for variables that should not be reassigned.

javascript Copy Edit let count = 10; const name = "JavaScript"; // name = "Python"; // This will throw an error Knowing when to use let vs. const helps prevent bugs and makes code easier to understand.

Arrow Functions Arrow functions offer a concise syntax and automatically bind this, which is useful in callbacks and object methods.

javascript Copy Edit // Traditional function function add(a, b) { return a + b; }

// Arrow function const add = (a, b) => a + b; They’re not just syntactic sugar—they simplify your code and avoid common scope issues.

Template Literals Template literals (${}) make string interpolation more readable and powerful, especially when dealing with dynamic content.

javascript Copy Edit const user = "Alex"; console.log(Hello, ${user}! Welcome back.); No more awkward string concatenation—just cleaner, more intuitive strings.

Destructuring Assignment Destructuring allows you to extract values from objects or arrays and assign them to variables in a single line.

javascript Copy Edit const user = { name: "Sara", age: 25 }; const { name, age } = user; console.log(name); // "Sara" This feature reduces boilerplate and improves clarity when accessing object properties.

Spread and Rest Operators The spread (…) and rest (…) operators may look the same, but they serve different purposes:

Spread: Expands an array or object.

Rest: Collects arguments into an array.

javascript Copy Edit // Spread const arr1 = [1, 2]; const arr2 = […arr1, 3, 4];

// Rest function sum(…numbers) { return numbers.reduce((a, b) => a + b); } Understanding these makes working with arrays and objects more flexible and expressive.

Promises & Async/Await JavaScript is asynchronous by nature. Promises and async/await are the key to writing asynchronous code that reads like synchronous code.

javascript Copy Edit // Promise fetch('https://api.example.com/data') .then(response => response.json()) .then(data => console.log(data));

// Async/Await async function getData() { const response = await fetch('https://api.example.com/data'); const data = await response.json(); console.log(data); } Mastering these will help you handle APIs, databases, and other async operations smoothly.

Array Methods (map, filter, reduce) High-order array methods are essential for transforming and managing data.

javascript Copy Edit const numbers = [1, 2, 3, 4, 5];

// map const doubled = numbers.map(n => n * 2);

// filter const even = numbers.filter(n => n % 2 === 0);

// reduce const sum = numbers.reduce((total, n) => total + n, 0); These methods are clean, efficient, and favored in modern JavaScript codebases.

Final Thoughts Learning these JavaScript features early gives you a solid foundation to write better, more modern code. They’re widely used in frameworks like React, Vue, and Node.js, and understanding them will help you grow faster as a developer.

Start with these, build projects to apply them, and your JavaScript skills will take off.

As web applications grow in complexity and scale, ensuring optimal performance becomes more challenging yet crucial. Performance issues can lead to poor user experience, increased bounce rates, and potential loss of revenue. This post delves into several strategies and best practices to optimize performance in large-scale applications.  1. Efficient Caching Strategies Efficient caching reduces the need to repeatedly fetch data from slower, more resource-intensive sources like databases or external APIs. By storing frequently accessed data in fast, temporary storage, such as in-memory caches, applications can significantly decrease latency and improve response times. Properly managed caching also helps distribute load more evenly , minimizing bottlenecks and ensuring more consistent performance under high traffic conditions.  2. Database Optimization Database optimization can enhance the performance of large-scale applications by improving query efficiency, data retrieval speed, and overall database management. Techniques such as indexing, query optimization, normalization, and partitioning help in reducing query execution time and resource consumption.  Additionally, employing caching mechanisms, load balancing, and proper database design ensures that the database can handle high volumes of transactions and concurrent users. This leads to faster and more reliable application performance.  3. Load Balancing Load balancing distributes incoming network traffic across multiple servers to prevent any single server from becoming overwhelmed, thus optimizing performance in large-scale applications. By evenly distributing workload, load balancers ensure efficient resource utilization and prevent downtime due to server overload.  Load balancers can intelligently route traffic based on factors like server health, geographical location, or session persistence, further enhancing scalability, reliability, and responsiveness of the application.  4. Asynchronous Processing  Asynchronous processing can optimize performance in large-scale applications by allowing tasks to be executed concurrently rather than sequentially. This approach enables the application to handle multiple operations simultaneously, reducing wait times and improving resource utilization.  By decoupling tasks and using non-blocking I/O operations, asynchronous processing can significantly enhance responsiveness and scalability. This ensures that the system performance remains robust even under heavy loads.  5. Frontend Optimization Frontend optimization minimizes page load times, reducing network requests, and enhancing the overall user experience. Techniques such as code minification, bundling, and lazy loading can reduce the size of JavaScript, CSS, and image files, speeding up page rendering. Implementing client-side caching, using content delivery networks (CDNs), and optimizing asset delivery improve data transfer efficiency and decrease latency. Employing responsive design principles and prioritizing critical rendering paths ensure that the application remains fast and usable across various devices and network conditions.  6. Monitoring and Performance Tuning Monitoring and performance tuning play crucial roles in optimizing performance in large-scale applications by providing insights into the system behavior, identifying bottlenecks, and implementing optimizations.  Continuous monitoring of key performance metrics such as response times, throughput, and resource utilization helps detect issues early and allows for proactive adjustments. Performance tuning involves fine-tuning various components such as database queries, application code, server configurations, and network settings to improve efficiency and scalability. Optimizing performance in large-scale applications often involves integrating a robust JavaScript widget library. These libraries can streamline the development process and enhance the application’s interactivity and responsiveness, making them essential tools for modern web developers. 

Endnote Optimizing performance in large-scale applications requires a multi-faceted approach. The approach involves efficient caching, database optimization, load balancing, asynchronous processing, frontend optimization, and continuous monitoring. By implementing these strategies, you can ensure that your application scales effectively. This will provide a seamless and responsive experience for users, even under heavy loads.
