TypeScript is evolving towards the same language and tooling goals as Dart has already achieved. I have worked with both, and I find TypeScript tooling to be years behind Dart (event with recent improvements of type inference and e.g. VS's intellisense). The main reason TypeScript got more adoption was the fact that it was built on top of JavaScript, and people could easily start mix-and-match with their JS code. While that is great for easier adoption, it may not protect your engineers on the same level as Dart does.
