Also note that Arrays in Flex are not typed (there's no concept of String[] or Number[]) so you can store any kind of data into an Array and mix it, too:
var arr:Array = new Array(); arr.push(123); arr.push("foo"); arr.push(new Date());
They should be compared with Java's ArrayList class rather than String[] or int[]. The ArrayList class also stores only Object references, and they need to be cast back.
I haven't seen much of this in AS2 though:
array.push(new Date());
... var myData:Date = Date(array.pop());
Is casting back a best practice? I think so.
