9 Best JavaScript Libraries You Should Know

JavaScript is a programming language that also conforms to the ECMAScript specification. It is an object-oriented computer programming language that is used for creating amazing and interactive effects for web browsers.

JavaScript is one of the core technologies of the World Wide Web, the other two being HTML and CSS.

If you’re aware of JavaScript and have used this programming language before, then you must have come across JavaScript Libraries.

JavaScript Libraries is a reusable piece of code that oftentimes has one primary use case. A library may consist of several functions/objects/methods, depending on the language.

If you’re looking for the best JavaScript libraries that you must know, then you have landed in the right place.

We have brought you some of the best JavaScript Libraries that will help you in different ways. Now, let us start with the list of 9 best JavaScript Libraries that you should be aware of:

Top JavaScript Libraries

1. Google Polymer

The Google Polymer is one of the most popular JavaScript libraries that allow developers to reuse HTML, CSS, and JS to add creative touches to the existing applications or create more creative applications.

Google Polymer is compatible with almost all available platforms. After installing Google Polymer, you may reuse already developed elements without taking into consideration how they were developed.

Moreover, you can also create your own custom elements through the help of polyfills i.e. web component specifications. Anyone using Google Polymer must have prior knowledge of node.js, npm, Bower, Git, and Polymer CLI.


Sounds like something that will work for animations, right? Yes, it is true, Anime.js is one of the best animation libraries that makes staggering follow-through animations so simple.

Although, Anime.js is considered to be lightweight it comes with a clean yet powerful API. The most important part of Anime.js is played by timings.

This JavaScript library works with SVG, CSS, HTML, DOM, and JS objects.

3. QUnit

QUnit is considered to be one of the most popular unit testing tools which facilitate testing any generic JavaScript code.

QUnit has become crucial as far as Javascript is concerned as JS runs web projects, and manual testing so many functionalities are next to impossible.

QUnit is powerful as well as easy to use. Moreover, Unit tests that you write for one application can be reused for other applications across the browser.

4. WinJS

Next in the list is another JavaScript library developed by Microsoft.

WinJS is an open-source JS library that allows developers in developing windows applications that can run in Windows 8 as well as Windows 10 versions.

The developers have a choice to lead either the entire package or the individual modules that they need for their application. WinJS is a high-performance library.

5. React js

Another best JavaScript library is React js.

This one is helpful in building user interfaces for web applications. React is declarative, efficient, and flexible which allows developers in building more complex UIs through the help of an existing piece of code, commonly known as components.

React JS is maintained by Facebook and a few other companies.

The major advantage of using React JS is that it is super fast as any changes made by the developer doesn’t need a reload to reflect.

6. Velocity.js

What comes to your mind when you hear velocity? Speed, right? Yes, you guessed it right.

Velocity.js is a fast performing engine that simplifies work for the developers by providing great website animations.

Further, Velocity.js is faster than CSS and jQuery. Velocity.js allows you to run a sequence of animations one after one, unlike, CSS AND jQuery where extensive coding for the same is required.

In fact, major websites like Uber, HTC, Whatsapp, and many more applications use Velocity.js in their UIs.

7. Verge 3D

Verge 3D allows the developers to create beautiful 3D visualizations on websites such as puzzles, UI and website layouts, animation, AR/VR, and much more.

You would be amazed to know that Verge 3D was used by NASA to create a 3D visualization of the Mars Lander.

Moreover, the toolkit uses realistic colors and PBR materials to reflect the most exquisite 3D web experience and thus helping the developers in creating attractive websites.

Verge3D uses WebGL for rendering.

8. Pixi.js

Pixi.js is another open-source, cross-platform 2D engine that helps in developing games and other interactive, animation-based websites.

Pixi.js is a super-fast rendering engine and uses WebGL for its performance, however in case the WebGL is not supported, you can instead use HTML canvas.

Pixi.js is easy to use as it makes even the complex functions into a simple and ready to use the library.

Anyone having prior knowledge of Adobe Flash can easily handle Pixi.js. Even many big animation names like Disney use Pixi.js to develop their digital content.

9. Blockly

Finally, we end our list with another creation of Google, Blockly.

It is a web-based visual programming editor. When the developer adds Blockly to the code, the library adds an editor to the app that represents code snippets like loops, expressions, variables, and more as blocks.

Blockly is one of the most useful JavaScript libraries. The special part is that Blockly has no dependency on the end of the server but it is a client-side library. Blockly helps gain computer knowledge because of its drag and drop editor.

That’s all!!! Hope that you would have got a greater understanding of different JavaScript Libraries from the above-given information.
