JS interop question. I can't use external function...

# webassembly

[Robert Jaros]

JS interop question. I can't use external function with array parameter like this external fun init(modules: Array<JsAny>): Unit, because array types are not supported. But I can use external fun init(modules: JsArray<JsAny>): Unit and create JsArray with the following "trick" (see thread).

[Robert Jaros]

I've defined my own plain JS module with this JS function:

function jsArrayOf() {
    return arguments
}

export {jsArrayOf};

Then I've declared Kotlin external function:

@file:JsModule("jsmodule.mjs")

external fun jsArrayOf(vararg obj: JsAny): JsArray<JsAny>

[Robert Jaros]

And now I can use my external init function with an array parameter:

init(jsArrayOf(..., ..., ...))

And it works fine. So why the compiler can't make the same trick and allow array parameters to external functions?
