How to prevent your JavaScript code from being stolen, copied, and viewed?

I’m aware its almost impossible to do something like that because JS is client side. However I’m sure some counter measures can be taken to prevent less experienced users from viewing the code. (something more effective than disabling right clicking)

I know there are measures that can be taken like this app . If you try viewing the script it blocks you somehow. How can I set up a block like this (or perhaps better) for myself?

I just want to prevent leechers :\

Answer 1

The best you can do is compress and obfuscate your Javascript using YUICompressor or similar. This will at least make it hard to read.
