Could you build this?
No Building a custom JavaScript runtime on top of Mozilla's SpiderMonkey engine demands deep expertise in systems programming, C++, and runtime internals.
What it would actually take: The system requires embedding Mozilla's SpiderMonkey C++ engine, binding it to an asynchronous event loop (such as libuv or Rust's mio/tokio), and implementing standard POSIX and WinterCG web platform APIs. The hardest parts involve cross-boundary memory management, garbage collection root handling, and thread synchronization between JS execution and OS-level I/O.
