This code should never run on your machine. :P

Then why are you obfuscating it or even worried about people deobfuscating it? This thread is about Javascript.

Dude, I write financial applications in Node. Node IS javascript.

These applications run on the back end. Some of the API facing VMs have been attacked and so to be honest I've configured them so that if someone did get access to them, they wouldn't find much. Maybe just some API keys I can invalidate. Although I probably won't do it -- an obfuscator like this could be very handy here.

Did you give a try of Deno. This is a JavaScript runtime but it produce a single binary. This would make sense in your case because it can be harder to inspect it.
