It’s worth noting that it’s no longer a user-friendly tool for making interactive experiences, though. The current version of Actionscript is working hard to be a Real Programming Language, with a lot more code to write to make anything happen. It feels like Java to AS2’s Basic, and you just can’t write stuff in AS2 any more.

(AS1 is gone too, it was something you had to write by selecting verbs in a massive dropdown, and good riddance to that.)
