JavaScript module pattern (inspiration: TypeScript, json2.js by Douglas Crockford)

module.js

var Module;
(function (Module) {
  'use strict';

  var Greeter = (function () {

    // Define the Greeter class:

    function Greeter(message) {
      this.greeting = message;
    }

    Greeter.prototype.greet = function (name) {
      return this.greeting + ' ' + name;
    };

    return Greeter;
  })();

  // Exports:

  Module.Greeter = Greeter;
})(Module || (Module = {}));
