Getting started with Node.js

What is Node.js?

Node.js is a buzzword in the software development industry and it has become a trend to develop enterprise level applications using Node. Some of the big companies are already converting their applications to Node. This seems to be good point to start to look in to Node.js.

This is an Open Source JavaScript runtime environment for developing server-side networking applications using JavaScript developed by Ryan Dahl in 2009. This uses Google Chrome V8 JavaScript Engine as Interpreter and libuv as the abstraction layer. Core libraries in Node.js itself are written in JavaScript. There is huge number of Packages available to use in Node.js with Node Package Manager (NPM). Node.js is cross platform, which can be deployed on Windows, Linux and OS X.
