  • Private methods cannot be called by public methods. To make
    private methods useful, we need to introduce a privileged method.
  • A privileged method is able to access the private variables
    and methods, and is itself accessible to the public methods and the
    outside. It is possible to delete or replace a privileged method, but
    it is not possible to alter it, or to force it to give up its
    secrets.
  • 1 more annotations...
  • • This pattern of public, private, and privileged members is
      possible because JavaScript has closures. What this means is
      that an inner function always has access to the vars and parameters
      of its outer function, even after the outer function has returned.
      This is an extremely powerful property of the language. There is no
      book currently available on JavaScript programming that shows how to
      exploit it. Most don't even mention it.
