I hope Dart lang team will jump into this wagon as one of first users.

Dart and TypeScript will be as irrelevant as JS. Why Dart if you can have Go/Scala/F#/Haskell/Ruby/etc. compiled to WebAssembly?

If. All languages you listed need GC, which won't be in the initial version of WebAssembly. In other words, you won't be able to compile Ruby to WebAssembly any time soon.

You will be able to compile Ruby implementation to WebAssembly, but you can already compile that to asm.js. That is different from compiling Ruby to WebAssembly.

Yes and no. You can have native VM for running WebAssembly's Ruby VM... Oh my god, that sounds horrible as I wrote it.. but it can certainly be better than asm.js.

In comparison with TypeScript, Dart has different semantic and less legacy debts than JS.

And I think the whole point of WebAssembly is to have a choice, not "perfect language".

JIT (generating code in memory as data and jumping to it) is one of a few things not very well supported in asm.js and presumably the initial version of WebAssembly, so Dart probably can't use the initial version and should wait.
