Question

Can any one Explain the Difference between the Array and ArrayCollection in Flex?

Answer 1

As per the liveDocs

The ArrayCollection class is a wrapper
class that exposes an Array as a
collection that can be accessed and
manipulated using the methods and
properties of the ICollectionView or
IList interfaces. Operations on a
ArrayCollection instance modify the
data source; for example, if you use
the removeItemAt() method on an
ArrayCollection, you remove the item
from the underlying Array.

So really they’re the same, but one has more properties and methods.
