2. What is node.js?
“Node.js is a server side software system designed for writing scalable
Internet applications, notably web servers. Programs are written on the server
side in JavaScript, using event-driven, asynchronous I/O to minimize overhead
and maximize scalability.” - http://en.wikipedia.org/wiki/Nodejs
