TypeScript and CoffeeScript, yes. Dart's a brand new C-like web language that is quite different, and has its own VM. Although, of course, you can still compile to JS. But unlike TypeScript and CoffeeScript, it isn't really an alternative syntax for JS, or annotations removed at compile-time.

Yes, I know and you are correct.

At a high-level, though, and in the case where browsers are the target platform, those aspects are largely implementation details.

With the rather large exception of filesize.
