Module pattern thingy

module.js

var ModuleName = (function ($) {
  // Constructor
  var module = function () {
    // to stuff when "new" is called on us
  };

  // Say hello
  module.prototype.say = function (name) {
    alert('Hello ' + name);
  };

  return module;
}(window.jQuery)); // Passing in globals


// USAGE

var sayer = new ModuleName();
sayer.say('simon');
