Just experimenting with publishing a package

var Stack = function() {
  // Hey! Rewrite in the new style. Your code will wind up looking very similar,
  // but try not not reference your old code in writing the new style.
  var someInstance = {
    length: 0,
    storage: {}
  };
  
  _.extend(someInstance, stackMethods);

  return someInstance;
};


var stackMethods = {
  push: function(value) {
    this.storage[this.length] = value;
    this.length++;
  },
  pop: function() {
    this.length && this.length--;
    return this.storage[this.length];
  },
  size: function() {
    return this.length;
  }
};
