Hi - I'm using a library which provides me an async iterator. I'm unsure how to model for await...of in kotlin/js.

here is the pure js sample code
const sub = await this.nats.jetstream().subscribe(subject, opts)

for await(const m of sub) { // what's the kotlin/js equivalent
const data = this.jc.decode(m.data)
switch (data.type) {
case "draw":
break;
case "clear":
log("clear")
default:
break;
}
}

Would appreciate any pointers or examples.

you'll need to implement a scope for it first

see
https://kotlinlang.org/api/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/promise.html

then you can call suspending functions just like you would in JVM or Android Kotlin

Looks like function sub - AsyncIterable

You can also take a look at our wrappers for that: https://github.com/studoverse/campus-qr/blob/01a2bc3629bf78e64b0d6cdb2640d5908dcc58cf/moderatorFrontend/src/main/kotlin/webcore/extensions/Async.kt

Thank you.

Since pre.556 AsyncIterable.iterator extension is available

for must work fine
