A: JavaScript, the way you most likely are using it, is a client side technology. That means that if you at all want to use JavaScript on your web site, it must be sent to the client in such a way that it can be read by the client machine and executed there. What happens at the client is not controllable by you - if the machine is able to read it, so is your user. Thus, any try at hiding the source code is futile. Anything you try to do to make it harder to read by the user is still not enough, because when the machine can read it out for execution, so can a user. So, forget all about trying to protect your source code. Place a copyright statement on it instead, that's the best copy protection that you will be able to find.
