is there a function like repeat that collects the output of the lambda it executes? shorter version of (1..times).map { ... }

[ephemient]

List(times) { ... }

[Joffrey]

You could use List(n) { i -> ... }

[Joffrey]

You beat me to it, was trying to format that crap on the phone 😆

[ephemient]

also

generateSequence { ... }.take(times)

if you want it lazily

[ephemient]

typing code on a phone is never great :-/

[Karlo Lozovina]

I think I'll go with List(times)

[Karlo Lozovina]

although, repeatMap could be usefull...

[Joffrey]

In what way would repeatMap be any different?

[Karlo Lozovina]

It wouldn't behave any differently... just a shorter name for the idiom

[Ruckus]

I'm pretty sure repeatMap is not shorter than List...

[Karlo Lozovina]

hah, true 😄 maybe only a bit more readable... maybe 😄

[todd.ginsberg]

You could always define your own extension for this, if you really want some syntax sugar:

infix fun <T> Int.times(fn: (Int) -> T): List<T> =
    List(this) { fn(it) }

val list = 10 times {
    "I am only kidding... or am I?"
}

[ephemient]

very ruby looking - but their #times is like Kotlin's repeat

[todd.ginsberg]

Yeah, for sure.
