Relationship with iterator-helpers #3

Closed js-choi closed 3 years ago

js-choi commented 3 years ago

The exciting iterator-helpers proposal has a similar toArray method that overlaps with this. (toArray already overlaps with Array.from too.) See #1.

My preference is to keep both toArray and Array.fromAsync (Array.from being a fait accompli). But we can explore this more before both proposals advance further. CC: @codehag

I think both should exist, too. One reason is that they’re not quite equivalent: Array.fromAsync will work with any object implementing the async iterable contract regardless of whether it inherits from AsyncIteratorPrototype.
