Using asyncawait (https://github.com/yortus/asyncawait):

    var bakeCookies = async (function(cookie_mix) {
      print("Baking cookies...");
      var oven = new Oven(cookie_mix);
      var cookies = await (oven.bake(15));  // bake for fifteen minutes
      cookies.decorate();
      return cookies;
    });

It's plain JavaScript, concurrent, and works with plain node.js, unlike StratifiedJS.
