Anyone knows a good tutorial about JS Array class and how to use it?

I know basic things about Array class, but i got stuck often on things like what happen with index that stored game object that got destroyed.

edit: the slot that the game object got destroyed returns null. still i appreciate a good tutorial about Array class :P

thanks in advance.

Also check out this article:

The properties of a destroyed object become null cause they lose the reference and are cleaned on the next call of garbage collector. I hope these are of some use for you:

also for in depth knowledge of js I recommend the book Head First Javascript, it have a lot of content and an easy to catch language, you can find it cheap on :]
