Node is a server-side JavaScript interpreter that changes the notion of how a server should work. Its goal is to enable a programmer to build highly-scalable applications and write code that handles tens of thousands of simultaneous connections on one, and only one, physical machine.

If you’ve heard about Node, or read any articles claiming how awesome it is, you may be wondering, “What is Node.js anyway?”. You may even still have questions about what Node is after reading their own home page. Node is definitely not for every programmer, but it could be the right answer for some.

This article will seek to answer what Node.js is by giving a brief background of the problems it is solving, how it works, how to run a simple application, and finally, where Node is a good solution. It will not cover how to write a complicated Node application nor be a thorough tutorial on Node. Reading this article should help you decide whether you should further pursue learning Node to use in your own business.
