We have a disagreement on the definition of "solves the problem". Having tried to refactor a codebase with heavy lodash use, that battle seems to be lost. Also, take a look at the async* construct here: https://www.dartlang.org/articles/language/beyond-async https://www.dartlang.org/articles/language/beyond-async Nothing similar is in TypeScript, and this is roughly a two-years old feature in Dart, not a fancy-new hype. I have used it couple of times, it is useful, and again: consistent across the board. Of course if you are happy with the limited promise support in TypeScript, go ahead with it. However saying that they are on-par is far from the truth.
