How to Inherit another Class' Properties using Prototyping.

DRY Penguins Creating a brand new Penguin was nice, but we did end up reusing a lot of the same code as the Animal class. This goes against the "DRY" principle of programming: Don't Repeat Yourself. Inheritance can help us here! A Penguin is an Animal, so they should have all the same properties and methods as Animal. Whenever this X is-a Y r
// 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();

How to use Prototype in Object

It's All in the Genes In object-oriented programming, inheritance allows one class to see and use the methods and properties of another class. You can think of it as a child being able to use his or her parent's money because the child inherits the money. We will learn more about inheritance as we continue this lesson, but for now let's just
// create your Animal class here
function Animal(name,numLegs)
    this.name = name;
    this.numLegs = numLegs;

// create the sayName method for Animal
Animal.prototype.sayName = function () {
    console.log("Hi my name is " + this.name);

// provided code to test above constructor and method
var penguin = new Animal("Captain Cook", 2);

Adding an Element in an Array using a Function.

Arrays of Objects Remember that an object is just another type, like a string or number but more complex. This means that just as we can make arrays of numbers and strings, we can also make arrays of objects. Here we have our Person constructor which should look familiar. We can use this constructor to make an array of Person objects, similar
// Our person constructor
function Person (name, age) {
    this.name = name;
    this.age = age;

// Now we can make an array of people
var family = new Array();
family[0] = new Person("alice", 40);
family[1] = new Person("bob", 42);
family[2] = new Person("michelle", 8);
// add the last family member, "timmy", who is 6 years old
family[3] = new Person("timmy", 6);

Creating new Object Using a pre-defined Function(Custom Constructor) 2.

Constructors in Review Constructors are a way to make objects with the keyword new. The most basic constructor is the Object constructor, which will make an object with no methods or properties. For more complicated objects we can make our own constructors and put in whatever properties and methods we want. Check out our example to the rig
function Rabbit(adjective) {
    this.adjective = adjective;
    this.describeMyself = function() {
        console.log("I am a " + this.adjective + " rabbit");

// now we can easily make all of our rabbits
var rabbit1 = new Rabbit("fluffy");
var rabbit2 = new Rabbit("happy");
var rabbit3 = new Rabbit("sleepy");
