I need to build a Weak-Valued cache for my KMP project; including Kotlin/JS, so I need weak references on each platform.

<https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.native.ref/-weak-reference/|WeakReference> is explicitly implemented for Kotlin/Native, to complement the existing <https://docs.oracle.com/javase/8/docs/api/java/lang/ref/WeakReference.html|JVM one>.
But I don't see any equivalent support for Kotlin/JS, even though JavaScript does provide a <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/WeakRef|WeakRef>.  Is there a way to make this usable from Kotlin?  Thanks.
I'm experienced in KMP/KMM (`expect`/`actual`), but new to JavaScript interop.

```external class WeakRef&lt;T&gt;(targetObject: T) {
    fun deref(): T?
}```

Thanks <@UJQB4DJF7> :ok_hand: It didn't occur to me about `external`
