Protecting objects in JavaScript

• IgorPartola 13y ago
  Here's another cool trick for making attributes of an object private: function MyObj() { var data = { id: 123, name: "Johnny Appleseed" }, obj = {}; obj.printName = function() { console.log(data.name); }; obj.changeName = function(name) { data.name = name; }; return obj; } x = MyObj(); x.printName(); x.changeName("Igor"); x.printName();
