Static Method or Singleton

        <p>You don't need a "new" operation to create object to use the method.</p>

        <pre data-sub="prettyprint:_">
        // A static method attached to the User object
        User.cloneUser = function( user ) {
        // Create, and return, a new user
        return new User(
        // that is a clone of the other user object
        user.getName(),
        user.getAge()
        );
        };
        </pre>


        <p>Another way to to do is like the following</p>

        <pre data-sub="prettyprint:_">
        User = {
        run:function(){ alert("run"); }
        }

        User.walk = function(){alert("walk");}

        User.run();
        User.walk();

        </pre>
