JavaScript was rated by IBM as one of the most worth learning programming languages ​​in 2017. Naturally, its popularity has risen rapidly and continues. This has also led to the generation of an active ecosystem and the development of related technologies and frameworks. Nowadays, there are so many frameworks and libraries. If you don’t have a general understanding of each framework, it may be difficult to make a choice. If you are trying to choose a suitable javascript framework, then you must not miss the following frameworks:

Angular

Angular JS is an open source front-end web application framework maintained by Google. It was originally developed in 2009 by Misko Hevery of Brat Tech LLC.

Angular JS is a model-view-controller (MVC) pattern framework that aims to make HTML dynamic. Compared with other frameworks, it can generate code quickly and test independent modules of the program very easily. The biggest advantage is that after you modify the code, it will immediately refresh the front-end UI, which can be reflected immediately. It is the most commonly used javascript framework for the development of SPAs (Single Page Applications). Angular JS is a full-featured framework and probably the most popular one. The disadvantage is that it is a bit difficult to learn.

React

React JS is not like a framework but more like a library, but it is definitely worth mentioning. AngularJS is an MVC framework, but ReactJS is a non-MVC framework developed by Facebook.

It allows you to create a reusable UI component. The user interfaces of Facebook and Instagram are developed with ReactJS. You can do very complex updates with React and the application will still run fast because the framework itself handles them very quickly.

You can also write many reusable small files instead of writing one big file. This is the best choice for large programs that deal with large amounts of data. One of the drawbacks of this framework is that it only handles the view layer of your application, so you may need to combine it with other tools.

MeteorJS

## MeteorJS was released in 2012 and covers all stages of the development cycle, including back-end development, front-end development, Database management. It is an open source framework written in NodeJS.

MeteorJS is a simple and easy to understand framework, all packages and frameworks can be used easily. All changes in the code layer can be immediately updated to the UI interface, and both the server and the client only need to be developed using JavaScript. He is mainly used for real-time application development for companies such as IKEA and Mazda. Not recommended for large or complex programs.

Vuejs

After understanding React and Angular, you can try to learn about VueJS, a progressive tool for user interface development JavaScript framework. It is a fast development and cross-platform solution.

Compared to Angular and React, it is proven to be faster and absorbs the advantages of both. The founder of Vue is You Yuxi, who once worked at Google and used Angular.

His idea is to directly extract the features of Angular that he likes, without introducing other complicated concepts and create a new framework. All Vue templates are based on HTML, and you can find many resources on GitHub. It also provides two-way binding and server-side rendering. In Vue, you can use template syntax or write rendering functions directly using JSX.

Node.js

Node.js is a server-side JavaScript runtime environment that works across platforms and is open source. The framework has an event-driven architecture capable of driving asynchronous I/O. It works in JavaScript runtime environment and hence shows similar properties of JAVA such as thread, package, loop formation.

Backbone

Backbone is an MVP model that relies on the Underscore.js library. It is designed to develop single-page web applications and ensure that different parts of the web application are synchronized. It uses an imperative programming style, unlike Angular which uses a declarative programming style. Backbone also updates synchronously with the backend code, so when the model changes, the HTML page changes accordingly. Backbone is used to build Groupon, Airbnb, Digg, Foursquare, Hulu, Soundcloud, Trello and many other well-known applications.

Choosing the right JavaScript framework is never easy, it depends on what features your app needs. Each framework has different features, and each has their advantages and disadvantages.

Ember.js

The Ember.js framework was created in 2011. It has been used to design websites for many well-known companies, including Kickstarter, Heroku, and LinkedIn.

Ember.js is updated regularly and provides a complete feature package. The framework is very effective for developing complex web applications, and its string-based template system helps reduce startup time. Ember.js focuses on scalability so developers can use it easily for mobile and web projects.

three.js

Want to create a 3D visualization but don’t need a full game engine? Three.js provides a lightweight 3D library for rendering 3D into an HTML5 canvas, SVG and WebGL. This is indeed a clear library, and there are hundreds of examples that work well in the use-case showcase for Three.js.

When to use three.js? Whenever you need a simple 3D visualization that can be output to canvas.

Mocha

Mocha is a JavaScript testing framework that makes it easy to test asynchronous code in node models and browser applications. Mocha tests can be run in tandem with high-quality traced exceptions for the right test cases.

Next.js

Next.js is not your usual JavaScript framework. It was developed by the React team as an add-on tool for server-side rendering. Using React and Next.js, developers can streamline the development process just like using the Vue.js framework.

Next.js comes with extraordinary features such as automatic code splitting and page-based client-side routing. Additionally, Next.js has full CSS support called styled-jsx, making user interface styling easier.

Polymer

Polymer is an open source JavaScript library developed by Google that allows you to create individual elements of a website without going into layers of complexity. In addition, it supports one-way and two-way data binding, thus opening up a wider range of applications.

Mithril

Mithril is a client-side JavaScript framework mainly used for developing single-page applications. The implementation of the framework is simpler since there are no functions derived from the base class. It's small (
