Popularly used by JavaScript coders to create real time Web API’s, Node.JS is a software platform mostly used for creating server-side applications. It features an event driven, non-blocking I/O model for real time applications, while supporting numerous protocols and real-time transport methods like WebSocket. Additionally, its multi-platform support including Linux, Mac OS X, and Windows make Node.JS one of the best runtime systems out there.

Strong Client-Server relation
In Node.JS, a powerful client-server relations saves you the hassle of having to switch between two or more technologies. This creates great ease for the developers because now they can work on a feature from beginning to end, eliminating the need for waiting for front/back-end to finish.

Node.JS delegates the laborious task of computation and managing I/O to the event loop, so that you can focus on the concept. This asynchronous nature of Node.JS makes programming simple and straightforward, and you can do away with the traditional threaded method which takes up more memory. Although complex node applications may be difficult to read at times, the Async JavaScript Libraries solve this issue by making the code easily readable as well.

Node.JS is built on the V8 JavaScript engine, which is very fast, reducing wait times.

Easy to understand
Node.JS uses JavaScript, which can easily be learned, highlighted by its immense popularity between both experienced and inexperienced programmers.
