5 Programming Languages of 2021

Python

Artur Yolchan, the Senior Software Engineer and proprietor of the site Coding Skills, says: "Python will likely be the most loved programming language for designers in 2021."

The expanded utilization of Python in a specific setting has a ton to do with that, recommends Alex Yelenevych, CMO of CodeGym: "In the improvement of man-made consciousness frameworks, Python has substantiated itself. Furthermore, numerous advanced and safe destinations are written in Python, and it is likewise exceptionally normal to learn in schools. The language is wonderful and very straightforward for fledglings, so its ubiquity will just develop."

It takes a ton to disintegrate the use of more seasoned, more generalist programming dialects, in any event, when fresher dialects start to draw in a ton of buzz, adds Matt Pillar, VP of Engineering at OneSignal: "Python is an old top choice, and it's not disappearing at any point in the near future. While occupants like Rust and TypeScript are involving increasingly more mindshare, removing some consideration from Python, Python keeps on being perhaps the most adored and most used programming dialects. With its solid association with information science toolbox, Python is being instructed at an expanding number of programming Bootcamp and is very much ready to be a most loved first language for engineers in quite a while to come."

In case you're absolutely new to Python, start your learning venture by making a beeline for Python.org, which offers a convenient amateur's aide. Microsoft has a video series, "Python for Beginners," with many short, Python-related exercises. There's additionally an assortment of Python instructional exercises and books (some of which will cost a month-to-month charge) that will show you the subtleties of the programming language (and remember your IDEs).

JavaScript

Michael O'Connell, Chief Analytics Officer at TIBCO Software, doesn't think the super famous JavaScript is going anyplace, particularly with regards to ruling engineers' mindshare in 2021:

The development of JavaScript as a plan and advancement climate has been sensational and will speed up in 2021. Regardless of whether you are chipping away at the front-end with JavaScript, applications, and structures with React, Angular, and vue.js, work area applications with Electron.js, or backend with Node.js, JavaScript is the ticket! You can even foster AI with Tensorflow.js.

I see the universes of self-administration BI and visual examination turning out to be perpetually pounded up in 2021 with (a) BI and investigation sellers giving consistent encounters to expanding their designs ranges as easy-to-change local abilities and organization, and (b) commercial centers for sharing augmentations across wide networks of training. The development of Vega (from the d3 pioneers) as a perception syntax and stage will help normalize and implement best practices across these networks.

Yelenevych concurs, referring to JavaScript's structures as a critical segment to its prosperity. "JavaScript—you can discover this language being used on pretty much every site. I think to React, effectively the most well-known JS frontend library will keep on acquiring prevalence. By and large, engineers love to make applications in React."

Without a doubt, it appears to be essentially sure that JavaScript will keep on filling in as the motor that controls the web past 2021, particularly as new ages of understudies use it for sites' prearranged conduct. A large number of sites will in any case depend on outsider JavaScript libraries and systems.

TypeScript

A counterpoint to the assumption JavaScript will continue its long-term popularity comes from Pillar, who reminds us TypeScript may start eating away at JavaScript’s dominance: “TypeScript offers a superset of JavaScript capabilities, and was introduced to extend the utility of JavaScript. TypeScript is easier to maintain than JavaScript as a result of its type safety features and has become the go-to language for greenfield, scalable frontend applications.”

Pillar adds: “While JavaScript is still the predominant language of the web, TypeScript is on its heels. As new applications are written in TypeScript and more and more legacy JavaScript apps are migrated incrementally, we can expect to see TypeScript surpass JavaScript in utilization in the years to come.”

Why is TypeScript so popular? With every passing version (it’s now up to 4.0), it continues to add new features that developers find insanely useful. No wonder that, in the 2020 edition of the Stack Overflow Developer Survey, some 67.1 percent of surveyed developers said that TypeScript was a programming language they loved, just ahead of Python (66.7 percent), Kotlin (62.9 percent), and Go (62.3 percent).

Whether or not you consider TypeScript an actual programming language (technically, it’s a superset of the ultra-popular and well-established JavaScript, but many programming language rankings treat it as a full-on language), it seems poised to dominate developer thinking in 2021 and beyond.

Go

"Among working experts, Go is the most famous desire language to learn by a wide margin. 32% of expert designers need to gain proficiency with the language" says Sachin Gupta, CEO and prime supporter of HackerEarth. Yelenevych says Go springs up with expanding routineness, making it a language to pay special mind to in 2021.

It's nothing unexpected that Go is famous. It was a top paying tech ability in 2019, and has extraordinary compared to other hourly rates for consultants. Created by Google longer than 10 years prior as a programming language that could join the most amazing aspects of different dialects, (for example, the runtime proficiency of C++ and the meaningfulness of Python), it's partaken in a consistently developing pool of designers who use it. In coming years, it may settle the score greater.

Kotlin

Kotlin came up regularly in our board conversation, and obviously, designers are watching this language intently, particularly given how Google's been empowering its utilization for Android improvement. "Android writing computer programs is about Java and Kotlin," Yelenevych says. "These two JVM dialects will drift."

Yolchan notes: "Kotlin is generally utilized for Android local application advancement. [Although] Android applications can be created utilizing Java 8, Kotlin is presently the favored language for most designers. We should likewise not fail to remember that Kotlin is a JVM-based language, and it upholds all Java libraries. In this way, creating backend administrations utilizing Kotlin likewise will drift, also."

Google's hug of Kotlin truly sped up things. "Kotlin is very much situated to assimilate the mindshare that has truly been coordinated toward Java," Pillar says. "Based on the JVM, Kotlin's compactness gives the language enormous broadness, from portable to worker side (using structures like Spring) to web frontends (through gathering JavaScript), Kotlin can work in an assortment of conditions. Designers love highlights like invalid wellbeing, coroutine support, and the blend of procedural and useful programming highlights."

AI Is Eating Software deepkapha.ai By Martijn van Attekum, Jie Mei and Tarry Singh Introduction Marc Andreessen famously said that “Software is eating the world” and everyone gushed into the room. This was as much a writing on the wall for many traditional enterprises as it was wonderful news for the software industry. Still no one actually understood what he meant.  To make his point he stated this example: "Today, the world’s largest bookseller, Amazon, is a software company — its core capability is its amazing software engine for selling virtually everything online, no retail stores necessary. On top of that, while Borders was thrashing in the throes of impending bankruptcy, Amazon rearranged its web site to promote its Kindle digital books over physical books for the first time. Now even the books themselves are software." Marc Andreessen This was 2011.  Marc Andreessen TechCrunch Interestingly, Andreessen also said the following: "I, along with others, have been arguing the other side of the case...We believe that many of the prominent new Internet companies are building real, high-growth, high-margin, highly defensible businesses." Marc Andreessen (Read the full blog article at his a2z VC fund) Little did Andreessen envision that the same software industry could be at risk of being eaten. Fast forward to 2019 and the very same software industry is nervous. Very very nervous! And the reason is AI. Especially for those who haven’t bulked up their AI warchest.  Acceleration Wave (2009 - 2019) - When Software Started Eating the World Andreessen was right.  The companies that embraced software in 2011 are the current market leaders in their respective fields, and the top 5 market capitalization companies worldwide in the second quarter of 2019 are all offering some type of software solutions (ycharts.com).  Concurrently, the period since 2011 has shown an unprecedented growth in the developments in AI. Although several key ideas about AI have been around for long, a number of processes have accelerated their potential use. First, computing power, in particular for specialized AI chipsets, has vastly increased. Second, the amount of training data for AI algorithms is exploding with the advent of data lakes and a fully connected internet-of-things world, expanding AI domains and decreasing the costs to train algorithms. Third, a large number of technological bottlenecks (such as vanishing gradients) have been solved over the last few years, massively increasing accuracy and applicability of existing algorithms. Lastly, the decrease in costs for cloud storage and computing plus the facilitation of distributed collaborative working, made combining highly specialized knowledge easier than ever before.  The extent in which Andreessen’s cherished software companies are weaving AI into their products is however often limited. Instead, a new slew of start-ups now incorporates an infrastructure based around the above mentioned AI-facilitating processes from their very foundation.  HyperAcceleration Wave (2019 - 2030) - AI Has Started Eating Software Driven by an increase in efficiency, these new companies use AI to automate and optimize the very core processes of their business. As an example, no less than 148 start-ups are aiming to automate the very costly process of drug development in the pharmaceutical industry according to a recent update on BenchSci.  Likewise, AI start-ups in the transportation sector create value by optimizing shipments, thus vastly reducing the amount of empty or idle transports. Also, the process of software development itself is affected. AI-powered automatic code completion and generation tools such as TabNine, TypeSQL and BAYOU, are being created and made ready to use.  Let’s quickly look at a few example applications of this hyperacceleration wave: Automating the coding process by having TabNine autocomplete your code with AI! DeepTabNine Tabnine It is trained on around 2 million files from code repository GitHub. During training, its goal is to predict each token given the tokens that come before it. To achieve this goal, it learns complex behaviors, such as type inference in dynamically typed languages. Once Deep TabNine developers realized the parallel between code and natural language processing, they implemented the existing GPT-2 tool which uses the Transformer network architecture. The inventor of this tool is Jacob Jackson, an undergraduate student and ex-OpenAI intern who quickly realized this idea and created a software tool for it. Getting answers to any question about your medical data As AI will create the query to get the answer for you! Here, a group of medical researchers created a tool that you can ask literally any questions on medical data and the AI generates a customized SQL query that is then used to retrieve the relevant data from the database. Speech Text to Generating Database Query automatically Question to SQL Generation It's called Question-to-SQL generation. They used RNN (a form of deep learning, an AI on steroids for text analytics) with Attention and Point-Generator Network. For those more inclined to exploring the technical part of this feel free to read their research here and software code here. So is it time the armies of database administrators (DBAs) to go home? Creating a beautiful website based on your sketch While AI translates your sketch into code! Want to build your website quickly? All you need to do is sketch it and this platform will use AI to create software code like html, css and js code ready in vue.js instantly. Sketch to create a website with AI Zecoda Easy, huh? Just input your sketch and voila! your website pops out at the other end! Find out more about this platform here. These are just a few examples of how AI is increasingly encroaching all parts of software development and eliminating mundane tasks of coding and programming rapidly! This is due to the motivation to automate the process of numerical analysis, data collection and eventually, processing and relevant code production. Researchers have higher-than-ever awareness and knowledge to infiltrate each and every problem at all levels with AI-powered software, from day-to-day anecdotes such as: Which kind of cookies shall we recommend to a customer given their shopping preferences? To large-scale, manufacturer’s dilemma, for example: How do we automate the production line in an individualized yet systematic manner? And finally, to the processing of building smarter, easier-to-use software that may even write code for you. Apart from assisted decision making, diagnostic and prediction, work of AI researchers and influencers have led to a hyperacceleration wave: Software powered by AI does not only achieve performances comparable to the human level, but creates something that would challenge an average person’s imagination and perception of their own abilities. A person can no longer tell apart the fake celebrity faces generated by generative neural networks from the real ones, or need not remember the name of every function they will use when writing a script. Imaginably, the wide application domains and near-human performance of AI-powered software will cause a paradigm shift in the way people deal with their daily personal and professional problems. Although some of us are pessimistic about, or in some extreme cases, consciously avoiding a world with overwhelming AI-powered software, there is not so much room for an escape. Amazon, Google, and even your favorite neighborhood florist, are actively (and sometimes secretly) using AI to generate revenue. Face it, or be left behind.   What would you do if you were BMW today? "At this point, no one can reliably predict how quickly electromobility will progress, or which drive train will prevail... There is no customer requests for self driving BEVs. (electric vehicles)" CEO, BMW A classic trap most big enterprises with established business fall for is getting micro-focused on existing business segments while losing sight on the slowly eroding economic and business climate. Tesla's story as an electric car is known to all but many may not know that it is the self-driving feature and the heavy use of AI in both software and hardware where the secret sauce lies. They have already driven 10 billion electric miles and the cars are collecting all the more data to disrupt not just the automotive markets but its adjacent markets in manufacturing, servicing, sales and in general mobility. Tesla's AI is eating all other automotive industry's business. A few weeks later after his annual address, the BMW chief had resigned. CEO's and executives who however do wish to proactively adopt AI should do the following 5 things Concluding thoughts 1) Have your AIPlaybook Ready Last year I did a keynote panel together with a few industry peers and I was asked if AI could eat software and I said "Yes". Take a listen. Any company that is not in possession of its AI Playbook, that is not armed with data, algorithms and machine learning models, is certainly going to find itself in serious quandary. An example of an AI playbook is to assess your firm's maturity thoroughly and plan for ROI driven projects. AI Playbook deepkapha.ai 2) Upskill and/or hire a (good) data science team Upskilling your staff to be able to drive your AI transformation is the key to success for any organization aspiring to become an AI company. We've advised several large-scale data-intensive projects and here are a couple of key arguments that executives should take to heart. In a couple of years embracing AI is not a matter of trend riding, but survival; To survive an era in which AI is dominating both market and software, CEOs and executives need to level up their mindset for successful adoption and application of AI within their enterprise, for which they either have to upskill or find a good data science team; Know your game: A good team helps you understand how AI will make your company survive; Examples are abundant in the industry and it is key for companies to pay attention to latest trends and launch several smaller projects to extract out the key projects that can be industrialized at scale. 3) Develop Algorithms & Execute Your Data-Play From Day 1 Upgrading your technical infrastructure that can develop the latest AI algorithms, process large quantities of heterogenous datasets, build and train both industry benchmarked and novel AI models is an important first step. Once that is established it is very critical to develop meaningful dialog channels to envision and dream project ideas that are pain killers and dive directly into solving those problems with data. Finally, executing from Day 1 on the "good-enough" data models and algorithms is where a true AI company can define its momentum and gain sizeable lead from its nearest competition. 4) Implement a distributed knowledge structure As access to the right data is a key to valuable AI solutions, ensuring access to data generated or acquired within the company and outside will be of crucial importance. Following this realization, pharmaceutical companies are starting to create central repositories of the data gathered in their clinical trials. Consequently, their data science teams will have access to a structured knowledge database they can use to train AI algorithms.  A second way to ensure the distribution of knowledge, is to set up a distributed collaboration structure. With the advent of software mimicking group processes from setting schedules, having meetings, or doing a brainstorming session, integration of knowledge and expertise should no longer be limited by geographical location. 5) Tap into AI start-ups with relevant knowledge Andreessen’s example of Disney buying Pixar in order to stay relevant has paid off for Disney, which sold for over 8 billion dollar in movie tickets this year, making Disney the second biggest media company (Forbes). Yet the latest developments suggest AI could also optimize movie-making processes. Moreover, as Disney is creating a consumer platform with Disney+, AI might form the necessary basis to ensure optimal usage of the data generated by this platform. When not wanting to build data science teams from scratch, collaborating with or taking over relevant start-ups might again be necessary for companies such as Disney to stay competitive. So yes, AI has started eating software.

Angular vs React in 2020

Before we dive in, it’s worth taking a moment to check on what our mighty warriors have been up to these past 12 months. Have they been slacking? Or training non-stop to be the best in the JavaScript frontend arena?

Angular 9 and beyond

Released in February 2020, Angular 9.0.0 has been long awaited by Angular devs. Angular 9.0.0 introduces a bundle of additions and fixes to Angular. Among other improvements, Angular 9 replaces the ViewEngine (VE) compiler with Ivy, Angular’s next-generation compilation and rendering pipeline. 

First, Ivy offers significantly improved performance. Second, Ivy includes a streamlined toolset for debugging, testing, and building large and complex web applications. It also helps reduce bundle sizes, especially for larger applications.

With Angular 10 just around the corner performance remains one of the top priorities for framework developers. 

React 16+

So, on one side of the ring, Angular is focusing on improved performance and reduced package size. On the other side of the ring, the latest React updates are focused on bug fixes and plugging potential security vulnerabilities. In addition, React 16+ attempts to improve asynchronous programming capabilities. 

Released in February 2020, React 16.13.0 includes numerous deprecation warnings for unsafe methods and components, as well as bug fixes, naturally. In terms of new features, the latest additions were already introduced in React 16.9.0, released in August 2019. The new features were focused on improved testing of asynchronous code and measuring performance.

Now that we’re all up to speed on the latest developments, we can take a deep breath, and dive in.

Library vs Framework

The first and main difference between Angular and React is in standalone capabilities and scope. Angular is a full-featured MVC (Model-View-Controller) framework while React is a lightweight JavaScript UI component library. 

In this sense, pitting Angular against React in the arena is akin to a Judoka facing a Sumo wrestler. Each has advantages over the other. But with each bringing a different approach and technique the winner is anyone’s guess.

What this means for you, as a web app developer, is that you need to consider the components and features you will need to have out of the box. Angular packs most of what an average web app needs on-install, and includes capabilities React does not, like built-in routing and dependency injection. React, on the other hand, is not as demanding in terms of structure and approach. Though it lets you offload less-critical functionality to other libraries, it also means adding dependencies and complexity to the project code.

Language

Angular was the first major framework to fully adopt TypeScript – a superset of JavaScript and statically typed language. You can write Angular applications in both JavaScript and TypeScript, but TypeScript is often the choice of programmers looking to make their code more compact and easier to debug than pure JavaScript.

React is based on JavaScript ES6+ and JavaScript XML (JSX) – a template language running on top of JavaScript. What makes JSX (supported also in Vue.js) unique is that it stores markup and logic in a single file. While some may find issues with this approach, JSX has a strong typing system to statically analyze code. This makes it especially friendly to new developers and those of us prone to typos (read: everyone). 

It’s worth noting that while you can use TypeScript in React, it is not natively supported.

Real vs Virtual DOM (vs Iterative DOM)

One of the most significant technical differences between React and Angular is how each manages changes in document contents, layout, and structure. While Angular makes use of a Real (HTML) DOM (Document Object Model), React uses a Virtual DOM. 

This difference in approach is perhaps one of the reasons why so many frontend developers prefer React over Angular. The virtualization of the DOM makes for significantly better runtime performance.

(Source: https://illustrated.dev/react-vdom)

With a real DOM, like in Angular, the entire tree structure of HTML tags needs to be updated whenever there are any changes. React instead creates a new virtual DOM whenever change is detected, and compares it to the “real” DOM. If the two differ, only then is the real DOM modified where the alterations were made.

The developers managing the Angular open-source project had no choice but to take note of this issue. More and more developers were switching to React to improve app performance. So action was taken. In the recently made official Angular compilation and rendering pipeline Ivy, you can implement an iterative DOM. This approach, while quite different from React’s DOM virtualization, can potentially save up to 30% runtime memory, especially with large Angular applications.

Unidirectional (Downward) vs Bidirectional Data Binding

Data binding is a technique to synchronize UI and logic. React uses one-way data binding (sometimes called Downward Binding) and Angular uses two-way data binding. 

The comparison between React and Angular in UI and business logic synchronization and data binding makes for a perfect representation of just how different the approaches are.

In Angular, changes to input in the UI can make changes to the model / component state and vice versa. In React, when you update the model /component state, the change will be rendered in the UI element. Modifying the UI element, however, will not affect the model / component state. You can change this functionality in React by using callbacks or state management libraries like Redux.

Bidirectional data binding may mean less code and less complexity in data flows. On the other hand, Angular can force the developer to be extremely careful and keep two-way data binding within a component. Without such care, you may find yourself with components in undesirable states and multiple sources of truth. These have a tendency to turn into long nights of bugchasing. 

(Source: https://www.cleveroad.com/blog/angular-vs-react)

This is just one of the many ways Angular tends to push developers into designing and coding their applications in a certain way. In contrast, React provides flexibility, but also depends on other libraries to enable added functionality. This dependency can, in turn, turn cumbersome with a growing stack of technologies, libraries and components that require constant upkeep.

Community & Documentation

This is not a popularity contest. Sure, when you compare frontend libraries, frameworks or even toothbrushes, odds are you will opt for the most popular and highly rated one. Toothbrushes and herd psychology aside, there are good reasons to consider the availability (and relevance) of both community support and official documentation. It helps if the documentation is good, or at the very least complimented by well-written tutorials and an active community on topical forums.

In this sense popularity does count and React is by far the more popular than Angular no matter what metrics you use. It has more stars and followers on GitHub, more downloads, and is listed as more beloved than Angular/Angularjs in stackoverflow’s 2019 developer survey by quite a margin. 74.5% of developers surveyed loved React, while only 57.6% expressed their affection for Angular/Angularjs.

Why is this significant? As you well know, pretty much all developers of all proficiency levels turn to Google and community forums with questions. This is in fact true for most professions today: when you’re not sure how to do something, Google it and/or ask in the right places online. 

With more users asking questions and answering them on the Internet, you have a better chance of Googling up a solution to your problem. In that sense, React has an edge over Angular. Having a larger user-base is not the only advantage React has. Being a Facebook project, it is frequently updated and documentation is available quickly.

Angular is managed by Google, which adds credibility to its reputation. However, since it is less favored by developers you may find yourself relying on available documentation that is insufficient for most.

For a developer considering which of the two they should learn there is an endless list of comparisons and discussion. If those aren’t enough, you can always add to them and ask the community what the right solution is for your specific requirements. We don’t need to tell you that at the end of the day, what matters is what you prefer as a developer, and what each project requires.

The Knockout

At this point, the Judoka and Sumo fighters in our metaphorical arena are giving us weird looks. Of course they are. The real battle here is not in the ring. It is between the frontend developers around the ring.

It’s worth noting that the differences we listed are only a handful of the properties that differentiate React from Angular. From licensing to backward compatibility and approaches to native app development – there are more differences than similarities, really. Especially when you consider that both are essentially used for the same goal – web application development. Very different means to an end.

If we had to pick a winner, it would be you, the web developer. Why? Because understanding the most significant points of distinctions between Angular and React puts you in a perfect position to select the fighter you want at your side as you tackle your next project.

Exciting New Tools for Designers, December 2019

As you are shopping this month for others, why not find a few goodies for yourself? Our roundup of new tools and resources is packed with usable items. And most are free, so there’s no shame in trying out something for yourself. Here’s what’s new for designers this month.

CSS Background Generator

CSS Background Generator gives you the tools – and code – to create an interesting animated background for digital projects. Demo 1 uses a fun web design trend with circular blobs with adjustments for color, size, and speed. Once you get the background set up in a way that works for you, show the code and copy it to your projects. Thanks go to Vincent Will for making a tool that functional and easy to use.

CameraBag Pro

CameraBag Pro just reinvented itself with a new release and features, making it a robust choice for photo editing. The Mac app is packed with editing tools and intuitive adjustments and custom presets (this might be one of the best features since you can instantly preview each before applying it). The tool works for photos and videos with styles that work for both types of images and batch processing tools (watermarks, resizing, and cropping). This is a robust image editing tool that makes quick work of adjusting images. This is a premium app, but one of the least expensive photo/video editing tools out there.

CodersRank

CodersRank creates a 360-degree coder profile based on the public and private data you hold on various coding sites. It creates visual charts that you can use to show off your credentials to potential clients or employers (or figure out what you know in relation to others in the industry). The site also includes learning tools and a job board.

Advent of Code 2019

Advent of Code is a seasonally-appropriate Advent calendar of programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language. Use them as a speed contest, interview prep, company training, university coursework, practice problems, or to challenge each other. There’s even a leaderboard to help you keep up with others.

Pantone Color of the Year: Classic Blue

Pantone’s Color of the Year for 2020 is 19-4052 Classic Blue. It’s a hue that’s probably a staple in many of your projects. Here’s how Pantone describes it: “Instilling calm, confidence, and connection, this enduring blue hue highlights our desire for a dependable and stable foundation on which to build as we cross the threshold into a new era.” This is one of the times that the color of the year has featured a color that is such a common one. The just released color guide includes swatches and tools in this classic color for 2020.

Wooof

Wooof is just for fun. Instead of spending time looking for cat videos in your downtime, you can spend it looking at the “internet’s biggest collection of open source dog pictures.” You can browse, save favorites and even look at the source code and API. Be prepared to get lost in this rabbit hole.

Realistic 3D Photo Cards

Realistic 3D Photo Cards is a pen by Jouan Marcel that uses hover effects and Vue.js to create cool cards that animate and move in a space with depth on hover. The motion is simple and realistic; you’ll want to fork it.

JetOctopus

JetOctopus is a tool to help you navigate technical SEO. It’s a SaaS crawler and log analyzer that helps you find website problems and prioritize solutions to improve your online presence.

The Svelte Handbook

The Svelte Handbook is a starting point for anyone who wants to learn about this newer web framework for building apps. Author Flavio Copes says: “The ideal reader of the book has zero knowledge of Svelte, has maybe used Vue or React, but is looking for something more, or a new approach to things.” And the guide is 100 percent free. So, get reading.

Universal Color Convertor

Universal Color Convertor is a Mac app that converts colors from HEX/RGB/HSL to other formats and code snippets (CSS, Swift, Java, C#, and Dart).

Slack Cleaner

Slack Cleaner can clean all the unused and space-eating files in your Slack account. It makes it easy to find and delete unwanted files with bulk delete functionality.

Terms and Conditions Generator

Terms and Conditions Generator helps create a professional and customized document that’s been designed by an international legal team. It works in eight languages and includes more than 100 clauses to work with.

CSS Scan

CSS Scan is a browser extension that lets you copy the CSS of an element on any website. It’s taking website inspection to the next level and works on pretty much any website, regardless of what it’s built on. The best part is that it even works with animation code by visualizing keyframe CSS without having to search through source code.

Botfront

Botfront is an open-source tool to build chatbots on top of the Rasa library. Design and implement conversations with a single step. You can run it on your laptop or servers. Plus, there’s plenty of documentation to guide you along.

StackShare API

StackShare API, a tool to get insight into the backend technologies a company uses, is still in beta and has a lot of potential application. (API scraping tools seem to be growing in popularity by the day.) Use it to build better custom profiles, generate leads, and learn about industry trends.

Webiny

Webiny is a serverless app form builder that works for creating simple and complex forms. Use it to create custom forms and validators, track revisions to forms, use the integrated ReCAPTCHA, integrate other apps, and manage submissions. Plus, everything works in an easy drag and drop interface.

Kampsite

Kampsite helps you get feedback from customers and website owners so you can make adjustments that they want with your product or design. Once a log starts, it’s easy to share ideas, upvote popular requests, and engage with users. The tool installs with just a couple of clicks and can help you create beter web experiences.

GooFonts

GooFonts is a tool that tags Google fonts for easy search using keywords, variants, and subsets. What’s cool about this project is that it can take some of the hassle out of finding the right Google Fonts in a quick and easy way. It just takes a couple clicks to return results that have the look you want with examples.

Reborn Display

Reborn Display is a vibrant handwriting style display typeface. The style is readable and just a little bit funky. It includes upper- and lowercase letters and ligatures.

Snowballs

Snowballs is perfect for a December roundup with a holiday theme. Each character includes snowflakes around the design and fun swashes and tails for end letters. It includes upper-and lowercase letters and numbers.

Snow Kei

Snow Kei is another winter-themed typeface with snowflakes in the letter shapes. It is a fun option for holiday-themed projects. The display font includes 156 characters.

Upwork Releases Latest Top 20 Fastest-Growing Skills for Freelancers

the largest freelancing website, today released its newest quarterly index of the hottest skills in the U.S. freelance job market. The Upwork Skills Index ranks the site’s 20 fastest-growing skills in a quarterly series. It sheds light on new and emerging skills and provides real-time validation of current trends in the labor market and tech industry. According to a new report, access to skills and talent scarcity are the biggest hiring challenges. “Labor markets overall are tightening, and for many skills, employers are increasingly struggling to find available workers in their local areas,” said Stephane Kasriel, CEO of Upwork and co-chair of the World Economic Forum’s Global Future Council on the New Social Contract. “As a result, the array of skills employers are finding through digital platforms is growing, including technical skills like Hadoop and Kubernetes as well as non-technical skills such as taxation and urban planning.” The 20 fastest-growing freelance skills in Q1 2019 experienced more than 170 percent year-over-year growth, while demand for the top 10 skills grew more than 370 percent year-over-year. The top 20 fastest-growing skills, Q1 2019 The fastest-growing skills cover a multitude of industries and emerging markets. U.S. Taxation Hadoop Robotic process automation Explainer videos Computer-aided manufacturing Financial planning Urban design Software documentation Salesforce Commerce Cloud Geospatial Julia development Kubernetes Magento Employee training Shopify templates Certified Public Accountant (CPA) Vue.js framework Leadership development Architectural rendering Podcasting Key Insights Tax reform, potential Recession spur growth in financial skills On the heels of the tax reform bill passed in 2018, U.S. Taxation (#1) was this quarter’s fastest-growing skill out of more than 5,000 freelancers offer on Upwork.com . Those unfamiliar with the new law tapped into the freelance talent pool to help navigate the transition and better understand the advantages and challenges of filing under the new system. Tax season also spurred demand for Certified Public Accountants (#16) and financial planning (#6) specialists. Automation Helps Capture Business Value Organizations are becoming more automation-savvy, earning robotic process automation (RPA) (#3) a spot on the index for the first time. Unicorns like Automation Anywhere and UiPath are providing solutions to large companies to help automate tasks and processes that have traditionally been done manually by humans. As RPA adoption increases among Enterprises, Forrester estimates that the market will grow to $2.9 billion in 2021 (from $250 million in 2016). Changing City Infrastructure Causes Spike in Demand for Urban Planning According to a report, 73 percent of all teams will have remote workers by 2028. As remote work adoption increases and more people are able to live and work where they choose versus where their work is, city infrastructure is also changing. Urban design (#7) specialists are helping keep up with this evolution by arranging and designing public spaces, transportation systems and amenities for residents, tenants and visitors. Geospatial (#10) technologies, which map and analyze the Earth’s surface, and architectural renderings (#19) also saw significant growth as the public and private sector alike look for ways to optimize […]

There is a favourite quote among social scientists that says, “It takes a village to raise a child”. What this means that a child learns from every interaction and its progress depends upon the support it gets from its environment. I am not a social scientist, but a software developer. Surprisingly, the same is true for software development. Using the right framework and foundational tools that command wide acceptance in the industry, helps to get support, guidance and resources, thereby reducing the risk of rework and unsupported components. Hence, for organizations involved in application development using Javascript frameworks, it is critical to be aware of the usage and popularity landscape of the multiple options available. Now is that time of the year when we get to evaluate for Javascript frameworks, what is going to be hot and what is going be not in 2019.

Having many open source options for Javascript, the landscape becomes murkier and hence more critical. Since there are numerous options and almost every framework has some advantage over the others, it becomes vital to know the criteria for evaluating them and accordingly make the right decision.

Once we have the right criteria in place, it becomes logical to decide which framework or combination of a framework, tools, and libraries will be suitable for a given application. In the following article, the Sitepoint team has done a great job in putting the criteria and listing out their views:

https://www.sitepoint.com/top-javascript-frameworks-libraries-tools-use/

There is no framework or library, which will perfectly fit your need. Hence, you choose one which meets your need as closely as possible and sticks with it for a while!

At Walking Tree, we follow this philosophy and help customers with a reason for our technology stack recommendation. We seek their input and review our proposal, which eventually helps the customer to finalize a technology stack, which they can stick with for their applications.

While selecting the front-end technologies, we guide our customers using the following features

Difference Between a Framework and a Library

Development Process and Tool’s alignment (for wireframe, prototype, development, theming, build, debugging, deployment, code minification, compressions, test automation, code coverage, etc.) with the selected framework/library

Active Community and the number of developers involved

Availability of commercial support

Training Availability and Product Documentation

Previous background of the people who are going to learn the technology

Size of the Project and intended duration of its usage

Browser support desired

Licensing Terms and Pricing

Data Access and Data Management Needs

Accessibility, Internationalization and other usability aspects

Based on the above criteria and our own experience with customers in the last 2-years, we have seen our enterprise customers adopting the UI development frameworks in the following order

Angular (after the release of 2.0)

Ext JS

React

We occasionally get an inquiry for Vue.js, but we are yet to see a lot of push for this. While comparatively, React.js looks more straightforward to learn, there are excellent training courses available for Angular and Ext JS. Sencha has multiple training courses on this topic to help people make effective use of the framework. By being a Sencha training partner in India, we have helped hundreds of developers in making effective use of Ext JS.

Overall, the web and mobile application development space continue to stay exciting. Every year the opportunity pool seems to be expanding. We are eagerly looking forward to the next year where we would love to build many more cross-platform applications aimed at phenomenal user experience.

V8 7.8, Node 12.11, and a Douglas Crockford book review

#456 — September 27, 2019

Read on the Web

JavaScript Weekly

The Making of a 13 Kilobyte JS Real-Time Strategy Game — Last week we linked to the 200+ entries in the recent JS13KGames contest, but if you’ve wondered how developers actually build such games, here’s a look behind the scenes.

Why JavaScript Tooling 'Sucks' — “JavaScript tooling is just too hard to use, and it’s not your fault,” says Shawn. JavaScript’s history, ownership, and target use cases have all had a role to play.

V8 Adding Support for Top Level await — This is only a link to a git commit but basically support for top level await is being added to V8 (and therefore a future version of Node). Node already supports this via the --experimental-repl-await option, but this should make it mainstream.

V8 Repo

A Look at V8 v7.8 — Every six weeks we’re treated to a look at the newest release of the V8 JavaScript engine. v7.8 continues to improve performance (such as with faster object destructuring) and has some improvements for WebAssembly users too (there’s now a way to use V8 solely as a WebAssembly execution engine from C/C++).

Ingvar Stepanyan

Node 12.11 Released: Worker Threads Go Stable — The underlying V8 engine has been updated to version 7.7 which results in some performance improvements and locale-aware support for number formatting with Intl.NumberFormat. Worker threads are now considered stable, too, which opens up a lot of new opportunities.

Node.js Foundation

Quick bytes:

The new executive director of the OpenJS Foundation is Robin Ginn, formerly an exec at Microsoft responsible for MS's engagement with the Node project.

The CEO of npm, Inc. has resigned and they're now looking for a new one.

Gatsby is now the richest JavaScript site generator in town as it has raised $15m in funding.
