Hey! I'm learning about coroutines and have a pretty simple question (I think). I want to do two tasks concurrently:

val first:  Deferred<Unit> = async { firstTask() }
val second: Deferred<Unit> = async { secondTask() }

first.await().let { doFirstStuff() }
second.await().let { doSecondStuff() }

In this example, will the doFirstStuff() always be called before doSecondStuff()? Or can doSecondStuff trigger as soon as second is evaluated (this is what I want to achieve)?
