# learning-oop-and-oloo-js

## add methods on the global Object so every new obj(regardless of how you create it) will have it by default

```javascript

// Place method inside the global Object so every new object will have that method by default

Object.prototype.greet = function(){

  console.log("hello "+this.x)

}

var obj1 = {

  x: "John"

}

var obj2 = new Object();

obj2.x = "Jane";

obj1.greet(); // hello John

obj2.greet(); // hello Jane

```

## create a "proto" object and use it to store all methods for other objects

```javascript

// create a "proto" object whith the sole purpose of providing methods to other different objectss

var proto = {

  greet: () => console.log('hello world')

}

var obj1 = Object.create(proto);

obj1.greet(); // hello world

/////

/////  "proto" with ES6 classes

/////

class Proto {

  greet(){ 

    console.log('hello world!')

  }

}

class Obj2 extends Proto{

  // your code here

}

var obj2 = new Obj2();

obj2.greet(); // hello world!

```
