What is Node.js

Node.js is a cross platform runtime environment and a library mainly to run JavaScript applications outside the browser. And this is used to create server side and networking web applications. Node.js is open source and free to use. And you can download the Node.js from this link https://nodejs.org/en/

Many basic modules of Node.js are written in JavaScript. Node.js is mostly used to run real time server applications.

And when we say about the official definition given in documentation is given below:-

?Node.js is a platform built on Chrome's JavaScript runtime for easily building fast and scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.?

Well Node.js, also provides rich library of various JavaScript modules to simplify the development of web applications.

Node.js = Runtime Environment + JavaScript Library
