Advanced JavaScript Deobfuscation

I need a javascript nodejs app to reads a hard obfuscated js file and change/reverse it to a clean human readable source code. The return result of the obfuscated and deobfuscated files (if evaluate) must be same.

Key requirements:
- Proficient in JavaScript and familiar with various obfuscation techniques
- Experience with both manual code analysis and automated deobfuscation tools
- Ability to simplify complex code for easy understanding
- Strong analytical skills

Your main task will be to work through this code and help me comprehend its functionality. Please, only apply if you have significant experience dealing with advanced JS obfuscation. Thanks!
