Got any useful benchmarks? Nobody is wondering which language to write their next "hello world" app in.
Just for the record I'm not saying Dart is amazing and everyone should use it, all I'm saying is that we should evaluate it objectively. If raw speed is your bottleneck then why are you wasting time evaluating Dart? Nobody is forcing anyone to use it, you can ignore it and move on with your day.
Dart won't be supported ubiquitously any time soon (if ever) which is why there'll always be a Dart->JS compiler. Why not just stick with vanilla JS or Harmony/ES6? I'd benchmark some bigger apps but they don't exist yet
