[Laszlo-dev] Any idea what this person is asking? Is pop() supposed to be defined by ECMAScript on associative arrays?

[Neil Mix]

I've never seen a JS implementation that allowed pop() on regular  
objects.  I can't even imagine how that would work -- how would you  
define ordering? FIFO? Alpha?

He might be confused about the fact that using a string as an index on  
an Array object treats it like an object property rather than an Array  
element.  That's a very good thing -- otherwise you wouldn't be able to  
extend the Array class -- additional methods would show up as array  
elements.  (Also a reason why using for(x in y) to iterate through  
array elements is a really bad idea.  but I digress.)

I've always thought that JS's treatment of Arrays is confusing until  
you've truly grokked how Objects work in the language.
