an_obj_pattern.js

var myClass = function(constructorParam) { return {
	/** object notation properties **/
	x: "it ",
	_state: 'awesome',
	
	/** Getters and setters! **/
	get state() {
		return this._state;
	},
	set state(value) {
		this._state = value;
	},

	/** init method **/
	init: function() {
		this.y = this.x + constructorParam;
		return this;
	}
}.init(); }

var objInstance = new myClass("works!");
console.log(objInstance.y); // it works!
