I'm having serious problems deobfuscating a JavaScript file at work. This file is inside a web app that I was left in charge of to improve it. The problem is that I can do it without having access to this file and the previous programmer that obfuscated it is not reachable.
I tried many ways of deobfuscation but none worked.
