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;
