//polyfill for Object.create

var developer = {
  	init: function (array) {
			this.languages = array
		},
		name:"john doe",
		person:true,
		languages:[],
		booze: {
			beer:"miller low life",
			whiskey: "jameson",
			getDrunk: function (howmanydrinks) {
				if (typeof howmanydrinks === 'number' && howmanydrinks > 4)
					return "your a trooper"
				else {
					return "your a lightweight"  
					}
			}
		}
}

developer.init(['css', 'html 5', 'javascript']) // her we initalize and pass array




var james = Object.create(developer);  we create a new object and it's prototype is developer
james.name = "James"; // append the new object
//delete james.name // if you delete the name property it will look to it's prototype which is John Doe
james.name // outputs James
james.booze.getDrunk(3) //outputs you're a lightweight
