02/14/2020, 1:57 PMOr implement an IntRange-backed List yourself since the getter is just min + index

02/14/2020, 1:59 PMThanks @jw
I don’t need to cache the result, since it is one time operation, but since it is during the component initialization. It would be nice to do it faster. Initially the range was small, but now it turned out that existing approach doesn’t work well 😄

02/14/2020, 2:05 PMthis is somewhat faster
Copy code
measureNanoTime {
val list = (5000..50000).toList()
}
measureNanoTime {
val list = (5000..50000).let { range ->
List(range.last - range.first + 1) { range.first + it }
}
}a
