With clientside javascript you can't as your code is distributed
in source form and is easily readable. With JScript, there is the
Script Encoder (see MSDN), but this is nothing more than obfuscation.
Attempting to disable the context menu does nothing to
protect your script in a Web browser.

Your code is likely protected under copyright laws. See:

Even with obfuscation, there are ways around this and you may even pay 
a performance penalty. Many modern JavaScript runtimes use a 
precompilation step to optimize code and I doubt they were designed for 
and sufficiently tested in this type of scenario. My suggestion is to 
move anything that you do not want available  in the client-side source 
to server-side processing. If your concern is infringement of your 
copyrights, use something other than HTML/JavaScript for your 
presentation layer.
