For JS interop, it would be ideal if we could adapt Dart Futures to implement the Promise interface.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise

This will also ease DOM interop as Promise becomes more common.

Ideally, Dart Future actually is a JS Promise, simply exposing different user-facing APIs (similar to Dart builtin List type and JS Array). But we could also try adapters, similar to Dart Iterable objects exposing a [Symbol.iterator]() method to JS, and Dart for-each consuming JS Iterables.

yeah, just wanted to add an update: this is something we're definitely doing, only question is when it happens. Probably after we've gotten the Dart language tests and modular compilation in a good place.
