Can one write a when statement and check if a list contains a value?
Like the following (pseudocode):

when {
    array.contains(value) -> {

    }
}

You can, if there's no initial argument to the when then each case or whatever just needs to provide a boolean

[Nir]

at that point though it's essentially identical to if else with extra indentation, pretty much

Ah thanks.
Instead I actually used the following, which is a bit simpler to read aswell

when (value) {
    in array -> {}
}

[Nir]

if (value in array) still seems quite a bit simpler to me, but hey, whatever you like 🙂

[Nir]

if value is coming from a complex expression another option is value.takeIf { it in array } which can be useful depending what you're doing

I'd guess that's not his only branch. A when never makes really sense with one branch 😄

[Nir]

yeah, taht's true, thought I'd still mention the takeIf in case though 🙂 But with multiple branches I'd still be inclined to if/else-if, really more because of indentation than anything else, but it's all to taste at that point
