[haXe] best strategy to port an existing js library

[Franco Ponticelli]

Yes, I think you are correct. The only two options are depicted in the
example below... any other idea?

// js library
function niceAlert(txt) {
  alert("### " + txt + " ###");
}

// haxe code
class Main {
    public static function main() {
    Main.msg("hello to you");
    Main.msg2("goodbye");
    }

  public static var msg : String -> Void = untyped niceAlert;

  public static function msg2(s : String) {
    untyped niceAlert(s);
  }
}

Franco.
