This stuff doesn't work. The agents read the AST and just ignore dead code. Even replacing all your function names at build time with decoys makes the agent see the juxtaposition.

You need evil context as well as evil names, and then you need to run the evil code! Not an appropriate defense on client sites.

To stop deobfuscation at scale, you're better off serving so many bundles that mass scraping can't scale, as they cannot reliably deobfuscate your code. This forces them into the browser and it's behavioural analysis from this point onwards.
