New vs Object.create

newobjectcreate.js

var pp = console.log
var Person = { name : "Frank Cadillac",
               greet: function() { return "Hello world, my name is "+this.name+"!!!";}
             }

// does not work!
// Person.prototype.getName = function(){
//     return this.name;
// }

var frank0  = Object.create(Person);
pp(frank0.greet());
//pp(frank.getName());
pp(Person.prototype)
// now with functions
//pp(frank instanceof Person)

function Mammal(name) {
    this.name = name || "Lebowski";
}
Mammal.prototype.greet = function () { return "Mr "+this.name+" says 'WOA MAN, BEVERAGE!'" }

var dude = new Mammal("The Dude")
pp(dude.greet());
pp(Mammal.prototype)
pp(dude instanceof Mammal)

function Politician(name) {
    Mammal.apply(this, [name]);
    this.name = this.name || "Douche McNonsenson"; // family name
}

Politician.prototype = new Mammal("MEGATRON!"); // for president
var frank = new Politician("Frank Underwood"); 

pp(frank.greet())
pp(Politician.prototype.name)

function create(o) {
    function F() {};
    F.prototype = o;
    return new F();
}
var robert = create(new Mammal("OPTIMUS"))
pp(robert.greet())
robert.surname = "Prime";
robert.getSurname = function() { return this.surname+"!!!!" }
pp(robert.getSurname())
var joe = create(robert);
joe.location = "here";
joe.getLocation = function() { return this.location+", which is a nice place" }
pp(joe.getLocation())
pp(joe.getSurname())

the whole point of prototypal inheritance is that you are inheriting from other objects.

Object.create/ create needs to be passed an object of some kind.
Remember Functions are first class objects in js

Also remember the prototype chain! (joe --> robert --> new Mammal("OPTIMUS"); )

So in essence Object.create just helps to create that prototype chain!
