A structured way to learn JavaScript.

I came across a post on Twitter that I thought would be helpful to share with those who are struggling to find a structured way to learn Javascript on their own. Personally, I wish I had access to this information when I first started learning in January. However, I am grateful for my learning journey so far, as I have covered most topics, albeit in a less structured manner.

N/B: Not everyone learns in the same way; it's important to find what works for you. This is a guide, not a rulebook.

I woke up this morning completely exhausted and my brain wasn't working. It wasn't until 4pm when I decided to just go on a walk for an hour that I felt ok. Dunno what's up with that...

Remember how I said yesterday that I'd get started on React? Well, I started to watch a video and the person went over the pre-requisites for learning React (i.e. what Javascript concepts you need to know), and I basically had to learn a lot of concepts related to ES6 such as arrow functions, modules, destructuring objects, spread operators, and other stuff, and I realized I knew none of those. So...I watched another video that went over all that, and while the video itself was only an hour long, it took me about 2-3 hours to get through it because I was constantly pausing the video and writing notes.

Anyways, this wasn't the first video by this guy that I've watched and I really like watching his videos for longer introductions to topics, so here's a link:

Arrow Functions in JavaScript ES6

JavaScript offers two primary types of functions:

Function Declaration

As we discussed in a previous post JavaScript Fundamentals .

If you want to check out the course : Course link

Function Expression

This allows you to create anonymous functions by omitting the identifier. Most often, these anonymous functions are stored in variables, like this:

const double = function (number) { return number * 2; };

In ES6, a game-changing feature emerges: the arrow function.

The Arrow Function Magic ✨

Arrow functions introduce a concise and expressive way to define functions compared to traditional function expressions.

The basic syntax is refreshingly simple:

(parameter1, parameter2, ..., parameterN) => expression;

Here's the breakdown:

parameter1, parameter2, ..., parameterN: These are the function parameters.

expression: This is a single expression or statement to be executed, and it's implicitly returned.

Let's dive into an example:

const add = (a, b) => a + b;

In this snippet, we've created an arrow function named add that takes two parameters, a and b, and effortlessly returns their sum.

Here are some important tips and tricks when working with arrow functions:

Single Parameters: If your function takes only one parameter, you can skip the parentheses, like so:

const square = x => x * x;

Implicit Return: For single-line functions, you can automatically return the result without using the return keyword. The expression comes after the arrow =>.

Brace-Free Blocks: If your function has a single-line block, you can omit the curly braces:

const cube = x => x * x * x;

With these principles in mind, you can transform code like this:

const volumeOfAHouse = (side) => { return side * side * side; }

Into this elegant form:

const volumeOfAHouse = side => side * side * side;

Arrow functions bring brevity and readability to your code, making ES6 a game-changer in JavaScript development.

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.

JavaScript 15 🧬 Arrow functions

New Post has been published on https://tuts.kandz.me/javascript-15-%f0%9f%a7%ac-arrow-functions/

JavaScript 15 🧬 Arrow functions

a - arrow functions introduction Arrow functions in JavaScript provide a concise syntax for writing functions They are part of the ECMAScript 2015 (ES6) specification. They offer several advantages such as more compact syntax, lexical this binding, and no need for the function keyword. They don't have their own bindings to this, arguments, or super, and should not be used as methods. They cannot be used as constructors and cannot use yield. They cannot be created as generator functions syntax: const functionName = (parameters) = // function body ; The parantheses around parameters can only be omitted if there is a single parameter const squareRoot = a = return a*a ; Curly braces can only be omitted if the function returns an expression const squareRoot = a = return a*a b - Arrow function examples Example 1 → concise syntax, omit parentheses Example 2 → concise syntax, omit curly braces Example 3 → Basic syntax Example 4 → with multiple statements Example 5 → `this` correctly refers to the person object Example 6 → arrow function in array method Example 7 → Arrow functions cannot be used as constructors. TypeError: Foo is not a constructor

Start Coding Today: Learn React JS for Beginners

Start Coding Today: Learn React JS for Beginners”—will give you a solid foundation and guide you step by step toward becoming a confident React developer.

React JS, developed by Facebook, is an open-source JavaScript library used to build user interfaces, especially for single-page applications (SPAs). Unlike traditional JavaScript or jQuery, React follows a component-based architecture, making the code easier to manage, scale, and debug. With React, you can break complex UIs into small, reusable pieces called components.

Why Learn React JS?

Before diving into the how-to, let’s understand why learning React JS is a smart choice for beginners:

High Demand: React developers are in high demand in tech companies worldwide.

Easy to Learn: If you know basic HTML, CSS, and JavaScript, you can quickly get started with React.

Reusable Components: Build and reuse UI blocks easily across your project.

Strong Community Support: Tons of tutorials, open-source tools, and documentation are available.

Backed by Facebook: React is regularly updated and widely used in real-world applications (Facebook, Instagram, Netflix, Airbnb).

Prerequisites Before You Start

React is based on JavaScript, so a beginner should have:

Basic knowledge of HTML and CSS

Familiarity with JavaScript fundamentals such as variables, functions, arrays, and objects

Understanding of ES6+ features like let, const, arrow functions, destructuring, and modules

Don’t worry if you’re not perfect at JavaScript yet. You can still start learning React and improve your skills as you go.

Setting Up the React Development Environment

There are a few ways to set up your React project, but the easiest way for beginners is using Create React App, a boilerplate provided by the React team.

Step 1: Install Node.js and npm

Download and install Node.js from https://nodejs.org. npm (Node Package Manager) comes bundled with it.

Step 2: Install Create React App

Open your terminal or command prompt and run:

create-react-app my-first-react-app

This command creates a new folder with all the necessary files and dependencies.

Step 3: Start the Development Server

Navigate to your app folder:

my-first-react-app

Then start the app:

Your first React application will launch in your browser at http://localhost:3000.

Understanding the Basics of React

Now that you have your environment set up, let’s understand key React concepts:

1. Components

React apps are made up of components. Each component is a JavaScript function or class that returns HTML (JSX).

function Welcome() { return <h1>Hello, React Beginner!</h1>; }

2. JSX (JavaScript XML)

JSX lets you write HTML inside JavaScript. It’s not mandatory, but it makes code easier to write and understand.

const element = <h1>Hello, World!</h1>;

3. Props

Props (short for properties) allow you to pass data from one component to another.

function Welcome(props) { return <h1>Hello, {props.name}</h1>; }

4. State

State lets you track and manage data within a component.

import React, { useState } from 'react'; function Counter() { const [count, setCount] = useState(0); return ( <div> <p>You clicked {count} times.</p> <button onClick={() => setCount(count + 1)}>Click me</button> </div> ); }

Building Your First React App

Let’s create a simple React app — a counter.

Open the App.js file.

Replace the existing code with the following:

import React, { useState } from 'react'; function App() { const [count, setCount] = useState(0); return ( <div style={{ textAlign: 'center', marginTop: '50px' }}> <h1>Simple Counter App</h1> <p>You clicked {count} times</p> <button onClick={() => setCount(count + 1)}>Click Me</button> </div> ); } export default App;

Save the file, and see your app live on the browser.

Congratulations—you’ve just built your first interactive React app!

Where to Go Next?

After mastering the basics, explore the following:

React Router: For navigation between pages

useEffect Hook: For side effects like API calls

Forms and Input Handling

API Integration using fetch or axios

Styling (CSS Modules, Styled Components, Tailwind CSS)

Context API or Redux for state management

Deploying your app on platforms like Netlify or Vercel

Practice Projects for Beginners

Here are some simple projects to strengthen your skills:

Todo App

Weather App using an API

Digital Clock

Calculator

Random Quote Generator

These will help you apply the concepts you've learned and build your portfolio.

Core proficiency in Vue.js

Although it may seem apparent, a strong grasp of Vue's fundamental features—reactive data binding, components, directives, and lifecycle hooks—is the cornerstone of any successful Vue developer. Additionally, a strong applicant should understand when and how to use Vue Router and Vue CLI. 

Make sure Vue.js engineers are at ease with Vue 3 and the Composition API before hiring them for long-term projects. For scalable applications, current IT businesses desire enhanced performance and better code organization, which the most recent version offers.

Deep knowledge of JavaScript and ES6+

Since Vue.js is based on JavaScript, knowing how to use contemporary JavaScript (ES6+) is essential. The ideal developer should feel at ease with promises, destructuring, array methods, arrow functions, and template literals. This guarantees their ability to write code that is clear, modular, and maintainable. Additionally, it's critical that they comprehend how JavaScript works with the DOM, particularly when responsiveness and performance are major considerations.

Experience in front-end ecosystems and tools

Vue is rarely utilized alone. It is frequently integrated by developers with testing libraries like Jest, Axios for managing APIs, and Vuex for state management. Proficient Vue.js developers should be able to use Webpack or Vite to create effective development pipelines. Knowing CSS pre-processors like SASS or LESS is also a plus because many tech businesses demand front-end engineers to know how to use them.

For this reason, it is essential to hire front-end developers who are knowledgeable with all aspects of contemporary online tools, not just the framework.

API integration and backend collaboration

The work of front-end developers is not isolated. They must communicate with RESTful APIs and backend systems with ease. Seek applicants who have experience working in teams utilizing Agile approaches and who are proficient in processing authentication tokens, testing API endpoints, and gracefully handling errors. To prevent a skills mismatch, be sure to include this criterion if you are working with an IT staffing agency.

Master JavaScript: Step-by-Step Tutorial for Building Interactive Websites

JavaScript Tutorial

Master JavaScript: Step-by-Step Tutorial for Building Interactive Websites

In the evolving world of web development, JavaScript remains one of the most powerful and essential programming languages. Whether you're building simple webpages or full-fledged web applications, JavaScript gives life to your content by making it interactive and dynamic. This JavaScript Tutorial offers a beginner-friendly, step-by-step guide to help you understand core concepts and begin creating responsive and engaging websites.

What is JavaScript?

JavaScript is a lightweight, high-level scripting language primarily used to create dynamic and interactive content on the web. While HTML structures the webpage and CSS styles it, JavaScript adds interactivity—like handling clicks, updating content without refreshing, validating forms, or creating animations.

Initially developed for client-side scripting, JavaScript has evolved significantly. With the rise of environments like Node.js, it is now also used for server-side programming, making JavaScript a full-stack development language.

Why Learn JavaScript?

If you're looking to become a front-end developer or build web-based applications, JavaScript is a must-have skill. Here’s why:

It runs on all modern browsers without the need for plugins.

It’s easy to learn but incredibly powerful.

It works seamlessly with HTML and CSS.

It powers popular frameworks like React, Angular, and Vue.js.

It’s in high demand across the tech industry.

This JavaScript Tutorial is your gateway to understanding this versatile language and using it effectively in your web projects.

Getting Started: What You Need

To start coding in JavaScript, all you need is:

A modern browser (like Chrome or Firefox)

A text editor (such as Visual Studio Code or Sublime Text)

Basic knowledge of HTML and CSS

No complex setups—just open your browser and you're ready to go!

Step 1: Your First JavaScript Code

JavaScript code can be embedded directly into HTML using the <script> tag.

Example:<!DOCTYPE html> <html> <head> <title>JavaScript Demo</title> </head> <body> <h1 id="demo">Hello, World!</h1> <button onclick="changeText()">Click Me</button> <script> function changeText() { document.getElementById("demo").innerHTML = "You clicked the button!"; } </script> </body> </html>

Explanation:

The onclick event triggers the changeText() function.

document.getElementById() accesses the element with the ID demo.

.innerHTML changes the content of that element.

This simple example showcases how JavaScript can make a static HTML page interactive.

Step 2: Variables and Data Types

JavaScript uses let, const, and var to declare variables.

Example:let name = "Alice"; const age = 25; var isStudent = true;

Common data types include:

Strings

Numbers

Booleans

Arrays

Objects

Null and Undefined

Step 3: Conditional Statements

JavaScript allows decision-making using if, else, and switch.let age = 20; if (age >= 18) { console.log("You are an adult."); } else { console.log("You are a minor."); }

Step 4: Loops

Use loops to execute code repeatedly.for (let i = 0; i < 5; i++) { console.log("Iteration:", i); }

Other types include while and do...while.

Step 5: Functions

Functions are reusable blocks of code.function greet(name) { return "Hello, " + name + "!"; } console.log(greet("Alice")); // Output: Hello, Alice!

Functions can also be anonymous or arrow functions:const greet = (name) => "Hello, " + name;

Step 6: Working with the DOM

The Document Object Model (DOM) allows you to access and manipulate HTML elements using JavaScript.

Example: Change element style:document.getElementById("demo").style.color = "red";

You can add, remove, or change elements dynamically, enhancing user interaction.

Step 7: Event Handling

JavaScript can respond to user actions like clicks, keyboard input, or mouse movements.

Example:document.getElementById("myBtn").addEventListener("click", function() { alert("Button clicked!"); });

Step 8: Arrays and Objects

Arrays store multiple values:let fruits = ["Apple", "Banana", "Mango"];

Objects store key-value pairs:let person = { name: "Alice", age: 25, isStudent: true };

Real-World Applications of JavaScript

Now that you have a basic grasp, let’s explore how JavaScript is used in real-life projects. The applications of JavaScript are vast:

Interactive Websites: Menus, image sliders, form validation, and dynamic content updates.

Single-Page Applications (SPAs): Tools like React and Vue enable dynamic user experiences without page reloads.

Web Servers and APIs: Node.js allows JavaScript to run on servers and build backend services.

Game Development: Simple 2D/3D browser games using HTML5 Canvas and libraries like Phaser.js.

Mobile and Desktop Apps: Frameworks like React Native and Electron use JavaScript for cross-platform app development.

Conclusion

Through this JavaScript Tutorial, you’ve taken the first steps in learning a foundational web development language. From understanding what is javascript is now better.

As you continue, consider exploring advanced topics such as asynchronous programming (promises, async/await), APIs (AJAX, Fetch), and popular frameworks like React or Vue.

[girldraki]

not sure if this is helpful but re: your headmates webpage, i did something similar on my site by making each about page a separate html file and using an <iframe> with the chosen page. there's a little bit of javascript to load a page in the iframe when a link or the next/previous arrows are clicked and that's it

we are actually using the isotope javascript library, which is theoretically capable of everything we want it to do and has a lot of nice out-of-box options, but unfortunately all the examples of "everything we want it to do" (filter by dropdown select, because we have way too many potential categories for buttons to look dignified (see below), combine this filter with quicksearch, sort functionality) are distinctly not combined in the various example codepens we have been shamelessly ransacking code from. so far we have successfully gotten the sort buttons and quicksearch to work at the same time but OH BOY does it not like when we try to add the filter select into the mix. this is probably not very hard to solve overall but considering we dont know how to do javascript basically at all it kind of has made us insane

this is completely dogshit on mobile, like don't-even-bother dogshit we havent made it responsive yet, but here is the headmates page as it currently exists-- it's got some neat functionality even though none of the links actually work lol. every time we try to add the <select> code it busts the entire thing so bad that it makes us, well, give up to go play sims

The book Eloquent JavaScript also covers ES6 in depth, while platforms like Udemy and Coursera offer structured courses for more in-depth learning. Practising with real-world projects is the best way to master ES6.

CSS & JS Frameworks

CSS and JavaScript frameworks play a vital role in front-end web development by streamlining the coding process and reducing development time.

CSS frameworks like Bootstrap, Tailwind CSS, and Foundation provide pre-written CSS classes and components for creating responsive layouts, navigation menus, buttons, and more. They help ensure consistent design and save developers from writing repetitive code.

JavaScript frameworks such as React, Vue.js, and Angular offer structured approaches to building interactive user interfaces and managing complex application states. These frameworks simplify DOM manipulation, improve performance, and enable the creation of reusable components.

By using these frameworks, developers can build modern, responsive, and scalable web applications more efficiently.

To learn CSS frameworks, explore the official documentation for Bootstrap or Tailwind CSS, as well as tutorials on freeCodeCamp and W3Schools. For JS frameworks, the React and Vue.js official docs, MDN Web Docs, Codecademy, and Scrimba offer excellent learning paths.

GIT & GITHUB

GIT and GitHub are essential tools for front-end web developers, enabling efficient version control and collaboration. GIT is a distributed version control system that tracks code changes, allowing developers to manage project history, revert to earlier versions, and work on multiple features simultaneously using branches.

GitHub is a cloud-based platform that hosts GIT repositories, making it easy for developers to collaborate, share code, and contribute to open-source projects. It also offers features like pull requests, code reviews, and issue tracking to streamline development workflows.

In front-end web development, GIT and GitHub are used to manage code for websites and applications, ensuring version control and seamless collaboration. They also make it easy to showcase projects in a professional portfolio.

To learn GIT and GitHub, consider GitHub Learning Lab, freeCodeCamp, Codecademy, and MDN Web Docs. Platforms like GitHub Docs and GitKraken also provide excellent guides and tutorials for beginners.

Responsive Design

Responsive design is a crucial aspect of front-end web development, ensuring that websites look and function well across a wide range of devices, from mobile phones to large desktop screens.

It focuses on creating flexible layouts, images, and components that automatically adjust to different screen sizes and orientations. This approach enhances user experience, boosts SEO, and reduces bounce rates by delivering a consistent browsing experience, regardless of the device.

Responsive design relies on key techniques like media queries, flexbox, and CSS grid to control the layout and structure of a website. Fluid grids and responsive images ensure content scales appropriately, while mobile-first design prioritises smaller screens before scaling up to larger devices.

Many front-end frameworks, like Bootstrap and Tailwind CSS, include built-in responsive design features, making it easier to create flexible layouts.

In modern front-end development, responsive design is essential, as mobile traffic continues to grow. It’s a core requirement for building professional websites and web applications.

React & Weather App Log # 1

Spent more of today learning React (this will be the theme for the next couple of days), but in addition to me watching videos and taking notes I decided to create a weather app! I can already tell this'll be a challenge, but that's good, right? Here's what I have so far, but obviously there's still a lot more to go. My biggest problem at the moment is figuring out how to structure the components and organize files. I'll definitely need to look at how other people structure their React projects, because I'm not 100% certain how small, numerous, or nested the components should be. Of course, I'm still a beginner so it's not the end of the world if I don't do things 100% correctly, but it definitely helps me make sense of everything seeing how things are organized. Anyways, that's all for now!

Oh yes, last note, but Javascript Arrow Functions are starting to make more and more sense to me the more I use them! I love this feeling of finally understanding something; it's very empowering.

Talking (only) about syntax I like C and Python. Pascal is fine/interesting. JavaScript is fine once you get what all the little points are, how arrow functions work etc... (Kotlin (seems (fun))). Ruby is fine.

Php is okay I $guess.

C# and Golang are meh.

I << don't << know << what << to << (say) << about << C++ 🖥️💥

Java is ugly. So ugly. ()()()
