Is there a way to create suspended iterators in Kotlin? Much like the for .. await in javascript?

Yes. In fact, Flow already does that. It's as simple as defining an operator fun MySuspendIterable.iterator(): MySuspendIterator and suspend operator fun MySuspendIterator.hasNext(): Boolean, suspend operator fun MySuspendIterator.next()

Very sweet! Thank you!

Is there any documentation on this anywhere? If not, could be useful 🙂

It's mentioned here, but not in great detail

Iterator support is mentioned, but I'm surprised that this includes suspendable Iterators 🤷‍♂️
