> AS3 added classes and static typing on top of ECMAScript, but lost out to regular ES3 in browsers.

That's a bit jumbled. AS3 was an early implementation of the ECMAScript 4th edition spec - Macromedia/Adobe implemented it expecting that the same changes would soon be coming to standard JS. ECMA later wound up abandoning that spec (for reasons unrelated to Flash), leaving AS3 sort of stranded as its own separate language.
