/*Exports
This next variation allows us to declare globals without consuming them and could similarly support the concept of global imports seen in the last example.*/

// Global module
var myModule = (function () {

    // Module object 
  var module = {},
    privateVariable = "Hello World";
  
  function privateMethod() {
    // ...
  }

  module.publicProperty = "Foobar";
  module.publicMethod = function () {
    console.log( privateVariable );
  };
  
  return module;

}());
