Hi,
its a conceptual difference, array maps indices to objects, while a
dictionary maps objects to objects.
There is no such thing as better, it depends on what you need.

An Array is a linear collection. A Hash is a random access collection
(lookup table) of name-value pairs.
Dictionary is a fancy Hash that can take an Object as a key, instead of
a String, and uses strict (===) equality for its lookups.
hash = new Object();
hash.foo = "bar";
array = new Arra

You got it! :)
You can mix and match with a Dictionary, as well. You can use strings
as keys or objects.

An associative Array behaves similar to a Dictionary.
(if you are using string keys)

Keys in an Array can be numeric, strings, or both:
var a:Array = [];
a[0] = something;
a["hello"] = somethi

On a sidenote, it's pretty easy to implement for as2 too btw, although the
performance is probably not uber.
I gotta admit once you get used to object-to-object mapping ... ;)

There's also a performance issue there, since some array operations(ie.
splice) are more expensive than in dictionaries and some dictionaries
operations(ie.
for in) are more expensive than array ones.

If you want the best performance you can get:

His doubly linked list is insanely fast. What I mean is, I had some code
that moved non-sequential items around a list. Using an Array, I could
easily cause Flash to timeout
