Example of a module pattern

moduleExample.js

var module = (function(input) {
	var localVariable = 4;
	var my = {};
	my.shout = function() {
		console.log('module.value is ' + this.value);
		console.log('input is ' + input);
		console.log('globalVariable is ' + globalVariable);
	};
	my.method = function() {
		my.value = localVariable;
		input = 8 / my.value;
		return [my.value, input];
	};
	return my;
})(globalVariable);;


var globalVariable = 0;
module.value = 0;

module.shout();
module.method();
module.shout();
