This code was deliberately obsfucated. So your confusion was actually what the authors wanted. Anyway, obfuscated code is not accepted by wikia according to their javascript guidelines, exactly because of this reason. It is easy enough for anyone to sneak in a tool to steal user's credentials or expose the computer to viruses and so forth. Aside from the fact that it is obsfucated, it is also not credited to the original author, which is also a TOU violation:

My suggestion is that you ditch this code and look for a better library, there are probably plenty of better tools.
