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. [TutorialsPoint] Here's a few key point regarding NodeJS, Developed by Ryan Dahl.   Created with the aim of creating real-time websites with push capabilities (websockets). NodeJS is an open source, cross platform runtime environment for server-side and networking applications. Build on V8 engine, Chrome’s JavaScript engine. Uses event-driven, non-blocking I/O model which makes NodeJS lightweight and efficient. Ideal for data-intensive real-time applications that run across distributed devices. NodeJS comes with several JavaScript libraries that help basic programming. NodeJS eco-system ‘npm’ is the largest in the world for open source libraries.   Let's...
