I don't think you understand functional programming.

    function makeAppropriateCar(cargo) {
      if(cargo == "people") return new Automobile();
      else if(cargo == "boxes") return new Truck;
      else ...
    }

    function makeLocalCar(settings) {
      var car = new Car({'color': settings.get('new_car_color')});
      car.set_origin(settings.get_hostname());
      return car;
    }

    function makeDebuggingCar() {
      if(global_settings.DEBUG && !global_settings.PRODUCTION)
        return new Car({'loglevel': LOGLEVEL_DEBUG});
      else if(global_settings.DEBUG && global_settings.PRODUCTION) // testing
        return new Car({'loglevel': LOGLEVEL_INFO});
      else  // production
        return new Car({'loglevel': LOGLEVEL_WARNING});
    }
