For anyone else running into this, there's a maintained fork of escodegen which doesn't have this issue: https://www.npmjs.com/package/escodegen-wallaby

Workaround:

• Fork this repository (example).
• bun install escodegen-wallaby && bun remove escodegen then find and replace require("escodegen") with require("escodegen-wallaby)".
• Remove dist from .gitignore.
• bun run build then commit and push everything.
• Add to your project with bun install $gh_username/js-confuser.

But it does have other issues related to the output - it's concatenating an identifier somewhere, obfuscated code breaks because there's various [object Object] dotted about. Not sure where to go from there.

Fixed in 2.0 (Currently 2.0.0-alpha.2). The 2.0 version nows uses Babel's parser and generator and is more suited for modern JavaScript syntax.
