`event-loop-spinner` is a tiny utility library for Node.js that lets developers periodically yield control back to the event loop while performing CPU‑intensive or highly concurrent JavaScript work. By calling `eventLoopSpinner.isStarving()` and `await eventLoopSpinner.spin()` inside tight loops, the library prevents the process from blocking I/O and keeps the application responsive—making it useful for backend engineers who need to safeguard network‑heavy services from event‑loop starvation.
