I've written both large ActionScript 3 (AS3) projects and large single page Javascript applications so I think I have a pretty good understanding of both languages.

For those of you who haven't done any AS3 programming it is a superset of the ECMAScript 4 standard while browser based Javascript uses ECMAScript 3.1. AS3 "feels" more like Java in that it adds syntax for types and classical inheritance but if you are lazy you can use * for the type and prototypical inheritance still works. Both of those might horrify static language/GOF purists but it does allow you to pass objects around on the side without refactoring pure OOP interfaces or inheritance trees.

In the end I enjoy working in AS3 with its static type checking more than I do Javascript pushed through JSLint. With large Javascript apps, even with strict use of the Module pattern, I feel like my code contains hidden runtime bombs waiting to do off.

Some caveats - I'm on a Windows machine and Flash runs great for me. I've also never developed with "use strict" in Javascript, which I probably should.
