Why async fn in traits are hard
Ehm. No. JavaScript will return a Promise. It’s “type” is Object as pretty much anything else in JavaScript.

But isn't a Promise for all intents and purposes the same as a Future here?

Yes, but I think they are emphasising that only a promise will be returned. Any further type information is not given

Check out structural typing. I would say it’s the type system JavaScript uses for non-primitive values. The “dynamic” appearance is just that JavaScript doesn’t center the type system in its UX.
