Help with Challenge

Challenge task 1 of 3

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.

    <script>


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

      function Car(model) {
        this.model= generic;


      }

      car.prototype= carPrototype;


    </script>

Looks good, except for one tiny thing. You are setting this.model to "generic" in the body of your function definition. Instead, use the model parameter you passed in, so the body says this.model = model; instead of this.model = generic;. Let me know if that helps! Smile:) Laura

You need to set Car.prototype = carPrototype;

and also as the previous poster said: this.model = model; in your constructor.
