stream‑iterate is a tiny Node.js utility that turns any readable stream into an asynchronous iterator, letting you consume stream items one‑by‑one with a callback‑style `read(err, data, next)` function. It’s aimed at developers who need fine‑grained, programmable control over streaming data—e.g., for custom processing like a streaming merge‑sort or other algorithms that require step‑wise access to stream values.
