The idiomatic way would be to use the Array constructor: Array(3) { index -> value }, which initializes the array immediately, so you can have a non-null component type.

Please allow a follow-up question, sorry. 😅

val squares = Array(8) { Array<Square>(8) { index -> Square(index, index)}}

index refers to the "inner" index - is there a way to get the "outer" index, so I could do Square(iOuter, iInner)?

[diesieben07]

val squares = Array(8) { iOuter ->
    Array<Square>(8) { iInner -> {
        // produce square
    }
}

nice, thanks

These things are just lambdas you are passing to the array constructor, they have normal lambda parameters.

[diesieben07]

You can even pass a function reference or anything you want, really.

still struggling a bit with the syntax, but I''m getting there 😅

[diesieben07]

Array(8, { index -> produceElement() }) is equivalent, but if the last parameter is a lambda, you can pass it outside the paretetheses.
