I installed Adobe Animate last week, it looks really similar to flash, they even use very similar concepts. I didn't try to write some code yet, but it looks like they use some kind of an action script.
It's basically Flash, it just exports differently. Same program, different name to avoid confusion with the Flash platform. Basically the only thing that's going away for the typical Animate user is the swf, everything else will remain as Animate exports to html5 and js while using as3.
