Another mapping question. Given

entries(): IterableIterator<[number, number]>

Could that be a

open fun entries(): IterableIterator<Pair<Number, Number>>

? Or should it be an array?

[Artem Kobzar]

No, you can map it only on Kotlin Array. In Kotlin there is no entity like IterableIterator.
In JS, IterableIterator it's an object which provide both [Symbol.iterator] and next methods.

[Artem Kobzar]

Also, you can try to use JsIterable type that placed in kotlin-wrappers

@Artem Kobzar thanks! I think IterableIterator is a recent addition in Kotlin Wrappers then

[turansky]

TS

entries(): IterableIterator<[number, number]>

Kotlin

entries(): IterableIterator<JsTuple2<Number, Number>>

I think IterableIterator is a recent addition in Kotlin Wrappers then

It’s old 🙂

Was added year ago

JsTuple

Every day I learn something new lol

And tupleOf - factory method

[Edoardo Luppi]

What would be a use case for emptyTuple ?

Payload of EventEmmiter.on async iterator

All JS and TS types, which you need for strict declarations are already here
