To directly answer your question - reverse engineering Javascript is OK.
For example: if you are working on solving, say, 7/8. You are totally allowed to reverse-engineer the Javascript to try and determine the password. Whether or not that is the intended method is up to you to figure out.
Hopefully that all makes sense.
