How can I obfuscate JavaScript?

Hi,

I want to compress a JavaScript code but not just to remove whitespaces also I want to change all variable names to unintelligible names. How can I provide this ?

Thanks in advance,

Compressing is one thing, and the process of changing variable names to unintelligible names is called obfuscation. For that, you will need to use a javascript obfuscator or yuicompressor which does both.

I dont know if you tried googling it but this what i use:

It is a good idea to have your code pass in JSLINT first to assure it works

Or Uglify, an alternative to YUI compressor that requires node.js.
