I use Javascript in Flash (AS2) and you can do some fantastic OO work with it. It even includes types to help with debugging. I wish Apple would implement JS instead of Applescript for things like Automator. Applescript is to obscure and counter intuitive to web developers and Flash coders who know JS, but don't know C well or Obj-C. It's a huge case of not invented here and a missed opportunity. Hopefully they learn from Dashboard Widgets...
