Javascript Prototype Chain / Inheritance

*Every Object has an internal link to another object called prototype

Creating an object:

Javascript Core Object ref:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Predefined_Core_Objects

syntax constructs:

var o = {a: 1};

//o ---> Object.prototype ---> null

var a = ["yo", "whadup", "?"];

//a ---> Array.prototype ---> Object.prototype ---> null

function f(){

return 2;

}

//f ---> Function.prototype ---> Object.prototype ---> null

Constructor:

function Graph() {

this.vertexes = [];

this.edges = [];

}

Graph.prototype = {

addVertex: function(v){

this.vertexes.push(v);

}

};

var g = new Graph();

//Graph ---> Graph.prototype ---> Object.prototype

Object.create

var a = {a: 1};

var b = Object.create(a);

// b ---> a ---> Object.prototype ---> null

var c = Object.create(b);

// c ---> b ---> a ---> Object.prototype ---> null

var d = Object.create(null);

// d ---> null
