mapAsync

Transforms all elements of the iterable concurrently.

For each element, launches a coroutine to apply the transform function.

Example:

val userIds = listOf(1, 2, 3)

val users = userIds.mapAsync { id ->
    api.getUser(id) // asynchronous call
}

println(users)

Note:

• One coroutine is launched per element, avoid large collections.

• If any transform fails, all other coroutines will be cancelled.
