Looks good.  But why are you returning true?  You don't have to, 
especially in a case like this where your function ALWAYS returns the 
same value.  Unlike some other languages (VBscript, for example), 
JavaScript lets you treat a function like a sub call, that is:

         x = doSomething(y);

or simply:

         doSomething(y);
