(ReferenceError: NewPenguin is not defined) I don't know exactly what's wrong, I was hoping for some help. Thank you in advance.


Penguin.prototype = new Animal();

var penguin = NewPenguin('bob')
Penguin.sayName();




// the original Animal class and sayName method
function Animal(name, numLegs) {
    this.name = name;
    this.numLegs = numLegs;
}
Animal.prototype.sayName = function() {
    console.log("Hi my name is " + this.name);
};

// define a Penguin class
function Penguin(name){
    this.name = name;
    this.numLegs = 2;
};

// set its prototype to be a new instance of Animal
penguin.prototype = new Animal();

var penguin = new Penguin('bob');
penguin.sayName();

On the second line:

var penguin = NewPenguin('bob')

This should be:

var penguin = new Penguin('bob');

It thinks NewPenguin is a variable, But you create a new object using the new keyword.
