facade implementation in JavaScript, Taken from Addy Osmani blog on design pattern

facade.js

var plugin = (function() {
	var _implementation = {
		id: 5,
		get: function () {
			return this.id;
		},
		set: function (_id) {
			id = _id;
		},
		run: function () {
			for(var i = 0; i < 5; i++) {
				console.log(i + " -- " + this.get() + " running");
			}
			this.jump();
		},
		jump: function () {
			console.log("I am some other method");
		}
	};

	return {
		facade: function (args) {
			_implementation.set(args.val);
			if(args.run) {
				_implementation.run();
			}
		}
	}
}());

plugin.facade({run:true, val:10})
