Difference between Array and ArrayCollection(Flex)

Question

What's the difference between array and arraycollection?

Answer 1

First, the ArrayCollection is designed for the Flex framework. It acts like a Proxy for a given Array instance. This means it can listen for modifications made to the source Array and update it self when this happens. It also contains a subset of additional methods required specifically by the framework (have a look at the IList implementation for instance).
