suspend fun sleepSort(list: List<Int>): List<Int> {

    val listInt = listOf(1, 2, 3)
    val listDeferred = list.map {
        GlobalScope.async {
            println("start $it")
        }
    }
    listDeferred.first().await()

    return listOf()
}

The above code gives me this result

start 1
start 2
start 3

I wonder why all deferred jobs are launched instead of jus the first one 🤔

list.map is not lazy -- it returns a List itself

[octylFractal]

if you want a lazily evaluated mapping, use .asSequence() first

ahh, right, thx

or specify CoroutineStart.LAZY on async
