As I think, JS array is just a hash-map which accepts only integral value as a key. And the .length property just return largest index + 1. Is this right? Is there any other differences? ...
Is there a performance difference between getting the count of an array (for example in c#) vs storing the count of an array in a variable. This is assuming that the count isn't changing.

Well, I'd like to be able to get a List of all Names, just like Dic...
