p‑map is a tiny utility for mapping over an iterable of values (or promises) with an asynchronous “mapper” function while limiting how many mapper calls run at the same time. It returns a Promise that resolves to an array of results (or an async iterable via pMapIterable) and lets you control concurrency, error handling, aborting, and skipping results—making it handy for Node.js/JavaScript developers who need to process many async operations efficiently without overwhelming resources.
