The rise of server side JavaScript

When first time I think about this it seems almost impossible, because as per my understanding JavaScript is client side scripting and it is execute by the browser. But the power of JavaScript has made it possible to have the server side JavaScript. This is very old concept it was first time introduce by Netscape Enterprise Server in late 1994 but Node.js has given more popularity to this concept. Moreover for Microsoft Azure has also adopted Node.js as development averment for cloud application.

Node.js is the server side JavaScript. Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, 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. We can configure node JS to listen event on request on particular port and provide response to the request without any sever !

Node.js is currently using V8 JavaScript engine which was develop by Google. The same engine is used in Google chrome to parse the JavaScript.

Node.Js is the only one example we can find more server side JavaScript example on:
