Comparisons of JavaScript Framework
1) AngularJS

It’s a framework launched by Google in 2009. With the help of this framework, it is easy to solve issues which happen while creating a one – page application. Why Angular JS is considered:

AngularJS, takes an edge over using HTML for defining web app’s user interface. It simplifies the entire web development process, defining specifically what you want.
The web application development is flexible by using directives and filters, which brings more functionality to HTML, and filters take care of the data transformations.
The unit testing, which is done in Angular JS, happens by inserting some mock data and, then measuring the entire output. This is mock data and then measuring the output.
Advantages of using AngularJS

Easy framework to test
Large Angular libraries
Simple routing
Data binding
It provides strong template building solutions
Drawbacks

Limited Routing
Scopes are difficult to debug
The page tends to be slow, when more elements are added
Third party integration is complex
2) ReactJS

ReactJS is an open-source JavaScript library, which helps in building a good performance. It is dependent on the aspect of ‘view’ in the Model View Controller (MVC) architecture, which was made to resolve the rendering issues of large datasets in JavaScript frameworks. Why ReactJS is considered:

ReactJS, can easily run on a server, with a virtual DOM being rendered, due to which it is easy to make the website more SEO friendly.
It runs on its own virtual DOM & takes care of all the changes or updates which are to be made in the DOM.
Advantages of using ReactJS

Get easily updated
Codes can be re-used
Easy to learn API’s & smooth UI
Component based architecture
Drawbacks

Limitations of integrating ReactJS into a MVC framework
Has always been touted as a library than, a framework
3) NodeJS

Node JS as we all know is a server, than a framework which is used to ease out the development of complex applications. Why NodeJS is considered:

NodeJS can easily handle multiple number of connections as it is used as a server side proxy
The NodeJS library is fast in executing the code
js ships with workhorse connectors and libraries such as those relating to HTTP, SSL, compression, filesystem access, and raw TCP and UDP. JavaScript, already tuned for a Web browser’s event loop environment for GUI and network events, is a great language for wiring up these connectors
The Node Package Manager is included with Node.js and has grown to a repository of nearly 50,000 packages, making it likely that another developer has already packaged up a solution to your problem, or even some less common ones.
Advantages of NodeJS
Built on Google Chrome’s V8 JavaScript Engine, Node.js is efficient and quick in code execution.
Single Threaded but Highly Scalable
No Buffering
Large files can be easily streamed
Simple to learn
