The best part of jQuery is the way it handles browser compatibility issues without the developer worrying about it. Some of the major IT companies like Microsoft, Netflix, and Google use jQuery. It is effortless to include jQuery in web pages.
The syntax of jQuery is similar to CSS syntax, making it the easiest one to learn, even for beginners.
3. Google polymer
Created by Google, Polymer is a JS library that allows developers to reuse HTML elements and create custom elements using HTML, CSS, and JS to create more interactive applications. It is compatible with different platforms. Once you install Polymer using the command line interface or the Bower method, you can reuse already developed elements without worrying about how those were created. You can also build your custom elements using polyfills i.e., web component specifications. The custom elements can be distributed across the network and used simply by importing the required HTML. To install and use Polymer, you should be familiar with node.js, npm, Bower, Git, and Polymer CLI.

Using this toolkit is an enjoyable and useful experience. It can create beautiful color-coded graphics with the necessary input information. You can get loads of effects without doing any extra coding. You can download the visualizations that you want instead of the entire package, making it not so bulky on the web pages. Since this toolkit is for data visualization, you might think it is useful for data analysts; however, you need some coding experience to use it.
D3 stands for Data-Driven Documents. With D3, you can apply data-driven transformations to DOM objects. The keyword with D3 is ‘data-driven,’ which means documents are manipulated depending on the data received. Data can be received in any format and bound with DOM objects. D3 is very fast and supports dynamic behavior for animation and interactions. There are plenty of already developed modules that give room for code reuse. D3 is flexible and exploits full capabilities of HTML, SVG (Scalable Vector Graphics), and CSS. D3 code is easy to debug as it uses the browser’s built-in inspector to show the path. Since D3 applies a declarative approach, it saves a developer many lines of code. D3.js is one of the most widely used JS toolkits as of now.
Pixi js can create stunning digital content. This open-source, cross-platform 2D engine helps create games and interactive, animation-based websites. Disney is one of the many big names that use Pixi to create their digital content. Pixi is a super-fast rendering engine and uses WebGL for its performance, however when WebGL is not supported, HTML canvas is used. Pixi is sturdy and straightforward as it hides the functionality of some of the most complex functions into a simple, ready to use the library. If you know Adobe flash, Pixi is the easiest thing to learn next.
This simple yet powerful JS library is mainly used to embed flash SWF files in HTML documents. It supports only SWF files, and no other media types can be embedded using SWFObject. There are two options – dynamic publishing and static publishing to add the markups. Many popular websites like Microsoft, YouTube, and more use SWFObject. To use this library, JS should be enabled on the user’s browser. SWFObject has many utility functions to do different tasks such as utilities to work with DOM or to identify if the latest version of the flash player is installed.
Cross-browser JS library and API that allows for the creation of beautiful animations, Three.js relies on WebGL rather than conventional browser-plugins. Through its library utilities, developers can include complex 3D animations on their website without much effort. Three.js include many features like geometry, lights, materials, shaders, effects, scenes, data loaders, animation, and much more. The library is a single js file. Since the source code is hosted on the GitHub repository, there is a lot of support and documents available for Three.js.
Web animation has become a breeze with velocity.js. It is a fast performance engine that simplifies website animations. It is free, open-source software. Velocity is as fast (or more) as CSS and jQuery, especially on mobile devices. We can run a sequence of animations one after the other in a neat way, unlike jQuery or CSS, where we need extensive coding. Uber, WhatsApp, HTC, and many more websites use velocity to power their UIs. Including velocity is simple – include the JS file.
10. React js
React is easy to understand and use the JS library to build user interfaces for web applications (front-view or model of MVC architecture). React is maintained by Facebook and a few other companies. React is declarative, efficient, and flexible enough to let developers build more complex UIs using the existing pieces of code, also known as components. React is fast and scalable, hence any changes to applications do not need a page to reload.
Vue js is based on the Virtual DOM model, much like React, and has a component-based architecture. Using templates of Vue.js, apps can be created faster. Vue also requires fewer lines of code for the same task that would need more code with other libraries. If you need a small application to be built in less time, Vue should be your perfect choice. By combining Vue with other tools and utilities, you can get a full-fledged framework. As a framework, Vue can handle complex functionalities like routing, build tooling, and state management.
Developed by Microsoft, WinJS is an open-source JS library that helps in the secure development of Windows apps for Windows version 8 & 10. Developers can load either the entire package or the individual modules that they need for their application. WinJS has a broad set of APIs to perform simple and complex tasks, some of them having a standard implementation (not specific to Windows). WinJS gives high performance, is a useful library to learn with a variety of controls and features.
A highly reliable library that allows for event-based two-way communication between the server and the browser window. It has a node.js server and the browser client library. It can detect disconnections and provides auto-connection support along with other significant features like binary support, channel support, and multiplexing support.
Blockly, a creation of Google, is a web-based visual programming editor. When added to the code, the library adds an editor to the app that represents code snippets like loops, expressions, variables, and more as blocks. The best part is that you can create custom code, and the output is syntactically correct in your choice of the programming language. Blockly has no server-side dependencies; it is a totally client-side library. Blockly helps gain computer knowledge because of its drag and drop editor.
Modernizr provides feature detection i.e., it tells you the JS, HTML, and CSS features that your browser has. This helps in knowing and avoiding the unimplemented features. Whether a feature is present or not is detected by using a Boolean property against each feature to be tested. For example, if the browser supports WebSockets, the corresponding property ‘Modernizr.websockets’ is real. There are over 250 features that can be tested using this library.
Adding the Verge3D toolkit, developers can create beautiful 3D visualizations on websites, for example, puzzles, UI and website layouts, animation, AR/VR, and much more. Bringing out the artist in you onto the screen has become so easy as Verge3D is interactive, and you don’t have to be a pro at coding. Moreover, the toolkit uses realistic colors and PBR materials to give you the most exquisite 3D web experience. Verge3D uses WebGL for rendering. Verge3D has been used by NASA to create a 3D visual experience of the Mars Lander.
