You can a sequence to avoid creating a temporary

List

if you're going with

forEach

.

In Kotlin

Sequence

are preferred way to preform lazy stream operations. As it not required Java 8, and included in Kotlin stdlib. You can obtain sequence from list via

asSequnece()

call like

listOf(1, 2, 3).asSequence()

My bad, thanks!

My brain actually converts

Stream -> Sequence

when I read it, so i didn’t even notice 😅

My too, but this is #getting-started 🙂
