I've enabled collection literals as a test and noticed the following:

assertEquals(emptyList(), ["bbb"])

Translates to JS:

assertEquals(emptyList(), listOf('bbb'));

While

assertEquals([], ["bbb"])

Translates to JS:

var tmp$ret$0 = emptyList();
assertEquals(tmp$ret$0, listOf('bbb'));

I guess this is because [] translates to inline fun <T> listOf(): List<T> = _emptyList_()
Why not instead map [] directly to emptyList()?

Personal note on collection literals: I don't see myself going back to functions, the literal is way too handy.

Eventually, we'll introduce operators of for standard library classes:

interface List<out T> {
    ...
    companion {
         inline operator fun <T> of(): List<T> = emptyList()
         ...
    }
}

and will resolve collection literals to them so the current behavior is the closest approximation we can get.
