The main advantage ArrayCollectionis the event collectionChange, which allows you to get the benefits of data binding to it.

Some others:

  • The ability to filter or sort the elements of a collection without changing or copying the underlying array.
  • An implementation ICollectionViewthat allows you to create a cursor and iterate with it.
  • datagrid/etc ( arrayCollections)
