Partial A basic JS-to-bytecode compiler and VM interpreter is vibe-codeable, but making the obfuscation robust, semantics-preserving across real JavaScript, and resistant to reverse engineering needs security and compiler expertise.
What it would actually take: Build a JS parser (e.g., Acorn/Babel), a bytecode compiler that lowers the AST into a custom instruction set, and a small VM runtime embedded in the output, plus tests on real-world code. The hard parts are preserving exact JS semantics (closures, exceptions, async, getters) and making the result resist deobfuscation, which requires experienced reverse-engineering and compiler skills.
