I found this An Introduction to JavaScript Object Notation (JSON) in JavaScript and .NET article to be very useful especially if you are new to JavaScript Object Notation (JSON)

Explore some of the Object Oriented Techniques of JavaScript, check this MSDN article, http://msdn.microsoft.com/msdnmag/issues/07/05/JavaScript/default.aspx, by Ray Djajadinata (Ray Hsieh).

Happy Scripting!!!
