Josh did most of the work here, Maria.This was just a variation on what he showed you earlier. When you use the Function.apply method, you should pass the 'this' reference as the first argument if it is needed. Inside a class instance method a 'this' reference is (usually) necessary because it usually needs to correctly refer to whatever 'this' is inside the function scope. If you're using the apply on a static method or 'global' function, then you would usually pass null here.
So when calling already from within the instance scope (e.g. from one method to another) you would pass 'this' as the first argument. But when calling from an external scope (like the example you had here) you pass a reference to the instance that the method belongs to.
