What is Node.js and Why to use it?
Node.js was developed by Ryan Dahl and other developers working at Joyent. It was first released in 2009 supporting only Linux. In 2011, windows version was released.
It is used to build fast and scalable network applications as well as data-intensive real-time web applications. All versions of Node.js are starting from 0.1.0 releases to 0.1.x, 0.2.x, 0.3.x, 0.4.x, 0.5.x, 0.6.x, 0.7.x, 0.8.x, 0.9.x, 0.10.x, 0.11.x, and 0.12.x. Before merging of Node.js and io.js, it’s last versions was Node.js v0.12.9.
V8 is written in C++ language and implements ECMA Script (ES5). V8 is used in Google Chrome and can be run standalone or can be embedded into any C++ application.
It means a Node.js site will never lock up and can support thousands of concurrent users. In this way Node.js plays the role of web server like Apache and IIS. Actually, Node.js allows you to process new requests without waiting for back-end services to respond.
Node.js is also great for mobile applications, which typically rely on an API server to service requests from thousands of devices at once.
