Example of the revealing module pattern

revealing-module-pattern.js

// ES5 example
var module = (function() {
  'use strict';
  
  var selectors = {    
    // object literal would contain selectors
    mySelector: '.banner'
  };
  
  var publicMethod = function() {
    console.log("I'm a public function you should see me in console, i can be called by typing module.publicMethod()");
  };
  
  var privateMethod = function() {
    console.log("I'm a private function you should see me in console but cannot access me via a function");
  };  
  
  var init = function() {    
    privateMethod();    
  };
  
  return {
    init: init,
    publicMethod: publicMethod
  };
})();

module.init(); // I'm a private function you should see me in console but cannot access me via a function
module.publicMethod() // I'm a public function you should see me in console, i can be called by typing module.publicMethod()
module.privateMethod() // module.privateMethod is not a function
