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: http://robotduck.wordpress.com/2009/11/04/88/

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: http://www.unifycommunity.com/wiki/index.php?title=JavascriptMultiDimArrays
