This article aims to explain the most popular client-side JavaScript frameworks. Which one is “best” for you is another question.
A framework is an application skeleton. It requires you to approach software design in a specific way and insert your own logic at certain points. Functionality such as events, storage, and data binding is normally provided for you. JavaScript Framework differs from a JavaScript library in its control flow:
[1] A library offers functions to be called by its parent code, whereas a framework defines the entire application design.
[2] A developer does not call a framework; instead it is the framework that will call and use the code in some particular way.
Some JavaScript frameworks follow the model–view–controller paradigm designed to segregate a web application into orthogonal units to improve code quality and maintainability. Examples: AngularJS, ReactJs, Ember.js.
Frameworks and libraries are useful because they help to build websites faster. A framework is just a level up on a library.Frameworks have predefined functions which make including a functionality in a site very easy.
Javascript frameworks can help architect our code so that it is modular (therefore reusable), DRY, readable, performant and secure and most importantly cohesive as well as easy to understand. jQuery is not a framework, so it doesn’t help in these regards. Bunch of frameworks now allow to define the data model and they will generate API for us. Sometimes its even possible to take client code and with little modifications convert to the mobile app using PhoneGap.
A modern JavaScript framework typically provides an API to handle the following high-level aspects of single-page application development:
As we know a number and variety of JavaScript Frameworks available this time, each with its own capabilities. Developers don’t use every framework, they use one or two frameworks. Not because that they are best, but yes either full fill their requirements or better than other frameworks. Here we are showing you some framework name and a brief introduction of them :
Angular Js :
AngularJS is a very powerful and open source JavaScript Framework. It is used in Single Page Application (SPA) projects. It extends HTML DOM with additional attributes and makes it more responsive to user actions. AngularJS is open source, completely free, and used by thousands of developers around the world. It is licensed under the Apache license version 2.0. Angular 2 is written in TypeScript and an MVC-type Framework. We can use it for any kinds of applications, but it would be an excellent idea to implement this particular framework for building highly complex front-end applications, though we can use it for back-end too. It is best when implemented for developing front-end applications that come with a singular modular Framework. AngularJs is developed by the Google. To learn or work with AngularJs, we must be familiar with HTML, CSS, Javascript, AJAX.

React Js :
React is a front-end library developed by Facebook. React Js is designed to create interactive UIs. It is used for handling the view layer for web and mobile apps. ReactJS allows us to create reusable UI components. It is currently one of the most popular JavaScript libraries and has a strong foundation and large community behind it. Now the reason behind choosing the react over other Framework is, Apps made in React can handle complex updates and still feel quick and responsive. ReactJs is modular.Instead of writing large and dense files of code, we can write smaller, reusable files.
React performs best where large programs that display a lot of changing data. React Js is scalable and flexible.
Ember Js :
Ember.js is an open source JavaScript client-side framework used for developing web applications. It uses the MVC ( Model-View-Controller ) architecture pattern. In Ember.js, a route is used as model, handlebar template as view and controller manipulate the data in the model.
Backbone Js :
BackboneJS is a lightweight JavaScript Framework that allows to develop and structure client-side applications that run in a web browser. It offers MVC framework which abstracts data into models, DOM (Document Object Model) into views and binds these two using events. The Backbone Js ships with only one dependency—Underscore.js, which provides the basic templates that Backbone.js builds off of. Backbone.js is extremely lightweight, and its small memory footprint makes it great for developing fast, high-performance single page web applications. While it lacks more advanced features like two-way data binding.
Phantom Js :
PhantomJS is a lightweight headless browser built on WebKit. It is called headless because the execution does not happen on the browser but on the terminal. Phantom Js is the solution for :
Babylon Js :
Babylon.js is a WebGL-based 3D engine it focuses on game development and ease of use. As a 3D engine, it has the tools to create, display, and texture meshes in space, and to add light sources and cameras. Because it’s game-focused, Babylon.js has some extra features that a regular 3D engine doesn’t require. It has native support for collision detection, scene gravity, game-oriented cameras (for example, a follow-camera that tracks a moving object), as well as native support for Oculus Rift and other virtual reality (VR) devices. It has a physics engine plug-in system, native audio support, a user-input-based action manager and much more.
The above-listed framework is popular frameworks but there are more frameworks present. Which framework is best suited for developing depends on what kind of website or web application you are developing. For example, if we are developing single page website then Angular Js is good for us because using Angular Js we can provide full navigation and all features we want to have without reloading the page. Every JavaScript Frameworks has their own advantages.
