Node.js

Node.js is an open source, cross-platform runtime environment for developing server-side and networking applications. Node.js applications are written in JavaScript, and can be run within the Node.js runtime on OS X, Microsoft Windows, and Linux.

Node.js also provides a rich library of various JavaScript modules which simplifies the development of web applications using Node.js to a great extent.

The main idea of Node.js is to use non-blocking and event-driven I / O so that they remain lightweight and efficient against real-time applications with a large amount of data running on distributed devices. In simple words Node.JS is used for specific reasons to fill particular needs.
