It’s very common that with every year, multiple JavaScript libraries and frameworks are introduced into the market. Among them, a few gain popularity and are used by app developers to develop latest applications/softwares, while others are left alone without any attention. The past few years had been incredibly amazing for JavaScript development as more and more new trends popped up into the world while new editions of the frameworks were introduced. Numerous frameworks, like React, quite seamlessly and gradually occupied the JavaScript domain and caused the obsolescence of many previous frameworks.

The web application development organizations always admire new frameworks and try to adapt to these new features to develop innovative applications both for themselves and for their clients. Even large enterprises/organizations, new startups, small-and-medium enterprises, and many other businesses look forward to the launch of latest and updated JS frameworks in order to have their apps developed using these new features. This is, to some extent, the key to successful business sustenance.

Therefore, it is indispensable to keep yourself updated with the most popular JavaScript tools and frameworks in order to be successful in 2020. It can also help avoid investing in frameworks that are obsolete in the market and gradually pick up a better substitute based on your software requirements.

Therefore, here we talk about few of the most popular JavaScript Frameworks in the year 2020:

1. Angular

Angular, which was developed and is maintained and updated by Google, is one of the most promising and popular JavaScript frameworks that helped developers consolidate JavaScript with HTML and CSS. Being an open-source front-end web framework, it allows software designers to assemble intuitive single-page web applications (SPA).

2. React

React, developed by Facebook, is yet another extremely effective open-source JavaScript library used to design intuitive user interfaces. This is a rapid developing library and is used by website admins to take care of the view layer of complicated websites and their applications. React is relatively faster than Angular and is handy for people who require basic, versatile, and quick frameworks for their work.

3. Vue.js

Known as one of the most commendable JavaScript frameworks. It is a lightweight open-source library, used to assemble innovative user interfaces. Vue.js is targeted to be quite versatile and make the user interface development process seamless and organized. Some consider it to perform better than both Angular and React and is predicted to overrule the market. Vue.js has an arrangement of highlights set up in such a way that they are less steep in expectations to absorb information, and involve simplicity of mixture with multiple programming languages.

4. Google Closure Library

Google Closure Library is another one popular, well-tested and verified module as well as a cross-browser JavaScript library developed by Google. A huge set of reusable user-interface widgets and controls are available to be used, including low-level features that enable manipulation of DOM, communication at server level, animations, data structures, testing of units, and many more. This library is designed to be compatible across most common IT systems and mainly uses Closure Compiler.

Since the Google Closure Library is open source, it’s possible to integrate the library in projects outside Google. It provides the base for JS libraries of different Google products, like Google Search, Gmail, Maps, Docs, Sites, Calendar, etc. Hence, for large or scaling up applications, this verified library can help prevent issues related to cross-browser compatibility and the minutiae of programming on the client-side.

5. VanillaJS

Well, first of all, this is a joke, it is not a framework at all. Like vanilla ice cream is basically plain, and “vanilla” in many slangs means “plain”. So, VanillaJS is just a plain JavaScript. In fact, all currently existing JavaScript frameworks and libraries are plugins for the VanillaJS framework :)

Knowing plain JavaScript, you can develop using React or Angular frameworks, but knowing only the Framework, you cannot effectively develop in plain JavaScript. It is as if you know English, you can read and understand the poems, but knowing only one poem, you cannot understand all English.

I’ve been working with JavaScript since 1999 and JavaScript is my favorite programming language.


Picking up a suitable framework for the purpose of your business from the vast range of JavaScript frameworks available in the market can be quite hectic at times. Over the course of time and increasing dynamics in customer demands, more frameworks are popping up within the markets and may add further to the ongoing race. Therefore, it is mandatory for developers to stay updated with the popular frameworks and get a hold on the features to ensure the choice is best suited for their application in hand. Every framework has its own advantages and flaws but we should simply focus on the necessities and functionalities of the framework before working with it.
