Anyone know a quick way to count the number of two dimensional arrays in a script?  i.e. foo[0], foo[1], foo[2], foo[x] - I'm looking for a method to find what 'x' goes up to, is there a built-in function to do this in javaScript?

I like to avoid recursion. Thanks.

Thanks.  I thought it was going to be more complicated than that!
