nonblocking is a Node.js utility that provides non‑blocking versions of common Array (and Dictionary) methods such as `forEach`, `map`, `filter`, `some`, and `every`. By processing large collections in small timed chunks and invoking a final callback, it prevents the event loop from being stalled, making it useful for server‑side or browser code that must remain responsive while iterating over huge datasets. It’s aimed at developers who need simple, synchronous‑style iteration without the latency penalties of traditional blocking loops.
