Rochak Chauhan::Unpredictably Exciting

This class is a collection of basic and commonly used functions in JavaScript. I coded this class just to validate a form in one of my sites. But it turned out to be more than helpful. I hope it will be of some help for all the web developers.

If you want a new function added or face any difficulty, feel free to contact me.
