2. Let's talk a little about Event-driven Programming
3. What is Event? Sometimes we want one object to perform its task as soon as something special happens in another object. This "something special" is called an event
4. How it works?
5. How to do that?! You ask OS to provide you the events related to your program!
6. OK, That's enough! Get back to Node.JS Wait! Do you know Javascript?!

What is Javascript? • Javascript as a toy language • The need for more powerful, more reliable and faster Javascript as web apps appeared. • Google Introduced V8 Javascript Engine • Javascript client side libraries and toolkits developed: Mootools, jQuery, Dojo • But all the above advances are limited to Browsers!
8. Node.JS: Javascript at server side • Node.JS is a framework, built on top of V8 javascript engine to run javascript codes at server side. • Goal: Building scalable network applications easier than ever!
