Arrays offer some additional functionality over using Objects
in certain cases (numerical indexing, sorting, usage as a stack
or queue, string expansion and concatenation). In these usages,
the native methods are typically quicker than anything written
in AS or even hand-coded FLASM, though this may vary for edge
cases like specialized sorts.
However, if you simply need a dictionary (a.k.a. asssociative
array), an Object works just as well with less cruft. Besides,
you have the added advantage of being able to hide certain
entries with the undocumented ASSetPropFlags method.
I tend to go with using Objects when I need a dictionary in AS,
though Arrays certainly do have their uses in certain cases,
say, string replacement:
newText = oldText.split('search').join('replace');
It's basically a matter of selecting the best tool for the job.
