A major point of OO in general is not to overuse/abuse it. That said,
your approach requires changing the underlying implementation, which
sometimes is simply not possible. Indeed the OP was just asking about
how to wrap a method.
Now, back to OO, the good of JavaScript is that you can easily and naturally
do that kind of stuff and more, while you just cannot do anything like that
in a purely OO language...
