Promises API in Node.js core: where we are and where we’ll get to
summary
Only FS and DNS have experimental Promise APIs in core right now, and wrapping others with util.promisify exists but feels clumsy; zero cost async stack traces are landed and some APIs are already converted. An events.once and async iterator PR targets event emitters. Work is tracked via a 50‑API catalog, an implementer survey and a user feedback survey, and multiple PRs are open — progress is real though the full migration and unhandled‑rejection semantics remain unresolved.
