Well, for starters, every JS file you make is a class. The compiler automatically wraps the content of the file in the correct bits to make it work.

If you want to create a seperate class within that (for example, if you want to organise variables in a more sensible fashion), you use this syntax-

 class MyClassName{
     var anInteger : int;
     var aBoolean : boolean;
     var aFloat : float;

     function DoSomething : float
     {
         return aFloat + anInteger;
     }
 }

Then, to use this in your script, make an instance like this-

 var anObject : MyClassName;
