ท่าใช้ factory function อะ ( อาจจะมั่ว ไม่ได้ลอง run )

dog.js

fucntion createDog(name, owner) {
  var dog = {
    name: name,
    owner: owner,
    init: function() {
      var me = $('<button>').addClass('dog').append(this.name).click(this.bark);
      $('#animals').append(me);
    },   
    bark: function() {
      alert(this.name + ': Bark bark. I love you, ' + this.owner + '. Bark!');
    }
  }
  dog.init();
  return dog;
}
