Unable to understand lines of javascript

Question

I am unable to understand a small code piece of JavaScript. Please help me to know the meaning of the following JavaScript blocks:

x = 2 + a / 30 >> 0;

What is the meaning of ">>" in JavaScript?

D = !0;

What is the value of D?

Format your code... people would have hard time understanding your code than you. — Thalaivar, Feb 05 '13 at 13:22
`What is value of D?` Have you tried running it? http://jsfiddle.net/7JXFs/ — apsillers, Feb 05 '13 at 13:29
`D = !0;` can easily be run using jsfiddle as @apsillers suggests, or just in console of your browser... (ctrl+shift+k in firefox) — akaIDIOT, Feb 05 '13 at 13:30

Not only JavaScript it is Shift operator generic to almost all programming languages..

Here is a link:

Example: 5 << 1 becomes 10..

(0101)b becomes (1010)b .. ie, 10 in decimal system
