In the JavaScript backend how to pass a array back as sequence?

[halloleo]

I have a JavaScript function which returns an JavaScript array, e.g.
    
    
    function give_me_three (dummy) {
       return ["one", "zwei", "trois"]
    }
    
    
    Run

How can I call this function in Nim? I all sorts of ways to make it work, the 
best (I think) is:
    
    
    proc give3(val: cstring): seq[cstring] {.importjs: "give_me_three(#)".}
    
    let three = give3("dummy")
    
    
    Run

it compiles, but doesn't seem to call `give_me_three` in the result correctly.

What's the best way to pass a array back as sequence?
