I think Typescript is in a different boat. All valid JS is valid Typescript, and Typescript is adding new JS features faster than browsers can. If JS ever catches up to Typescript it'll be by becoming Typescript, basically.
Why? It is evolving. Slowly, but it is evolving.
Enough to cast a doubt on the viability of Dart and Typescript.
