Constructor Function

Can someone please help me with this Challenge:

"Modify the 'Car' constructor function so that it takes an argument for its model and set its 'model' to the model passed in from the argument."


      var carPrototype = {
        model: "generic",
        currentGear: 0,
        increaseGear: function() {
          this.currentGear ++;
        decreaseGear: function() {

      function Car() {

  function Car(model) {
    this.prototype = carPrototype;
    this.model = model || carPrototype.model;

console.log((new Car("Mazda")).model);
console.log((new Car("Sedan")).model);
console.log((new Car()).model);

Ah...that worked and i like the way ity is written out, i understand it,
