Eh? Dart was trying to replace JavaScript in some fashion, but that obviously failed (they had good intentions, but bad execution). Seeing that Chrome hasn't included it yet, I doubt it will. So that dream is dead.
Dart is a replacement for GWT at this point. See AdWords being written in dart now[0]. Though it's not clear now Flutter.io will play into all this (that's targeting mobile with no web target).
As for typescript, Google actually embraced that fairly heavily with Angular2 being written in it.
