It doesn't matter - Dart can compile to JavaScript.
When it might matter is if there are apps (like games) that run faster in a Dart VM than in javascript. Anyway though, even Chrome doesn't include a Dart VM yet by default, so no big deal yet.

As well as, forcing developers to infer the way Dart compiler generates JavaScript code, in the absence of source maps.
I rather use JavaScript, thank you.
