regarding union types: I suppose you can cover the vast array of options using overloading? E.g

function x<T>(param: Array<T> | Record<string,strings>)

could be implemented as

external fun <T> x(param: Array<T>)
external fun x(param: Record<String, STring>)

correct?

In common case ReadonlyArray instead of Array - is what you need.
Especially for function parameters

It's like List (ReadonlyArray) and MutableList (Array)

[Bernhard]

ah, I understand, I was looking for MutableArray

Same situation with Record - we have ReadonlyRecord
