What should I use instead of

GlobalScope

in Kotlin/JS? I can't seem to find any other `CoroutineScope`s to use...

GlobalScope is discouraged, because it’s better to create your own scope whose lifecycle you control. For example,

MainScope()

or

CoroutineScope(Dispatchers.Default + SupervisorJob())

Is that because if I write

GlobalScope.launch { ... }

the resulting job won't get canceled? Is that because...

GlobalScope

never canceled?

Can you use the promise builder? https://kotlinlang.org/api/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/promise.html

Is that because...

GlobalScope

never canceled?

Yes
