The Flash IDE was top notch. And the fact that it made a one-file executable was pretty cool too. And their version of javascript with classes was damn cool (was it es6?).

Flash had a nice dev-to-executable experience, too bad it was soured by its browser inclusion. It could've been a great alternative to Java/Electron as the build once run anywhere lang. Adobe was a bit too early with Air

AS 3.0 was ecmascript and similar to typescript! I loved actionscript 3.

AS 3.0 was the closest we got to an ECMAScript 4 implementation.
