How I can describe static methods for JS classes?

[bashor]

turansky: companion objects allowed on external classes and members of companion object interpreted as static members

[bashor]

external class A {
    companion object {
        fun foo()
        val bar: Int
    }
}

fun test() {
    A.foo()
    A.bar
}

Will be translated to:

//...
function test() {
    A.foo();
    A.bar;
  }
//...

What about interfaces?

[turansky]

companions for external interfaces not allowed till Kotlin 1.1.2?! Right?

[bashor]

Yes, it’s prohibited since 1.1.2 because we think that external interfaces are not existed at runtime so it’s slightly strange to have any nested declaration inside.

[bashor]

Honestly, I don’t remember what compiler was generated for such cases before

[bashor]

If You have use cases for that feel free to share them here or in https://youtrack.jetbrains.com/issue/KT-16012
