// Object literal pattern aka Singleton
var Animal = {
  speak: function(words){
  	console.log(words)
  }
}

// Module Pattern
var Animal = (function(){
  var internalVar = 1;
  
  var getVar = function(){
   	return internalVar; 
  }
  
  return {
    getVar: getVar
  }
}());
  

 // AMD Module Pattern
define('Animal', function(){
  var internalVar = 1;
    
  var AnimalObj = function(){
    var getVar = function(){
    	return internalVar;  
    }
  }
  
  AnimalObj.prototype.getVar = function(){
  } 
  
  return AnimalObj;
  
});

var Animal = require('Animal')
