extra‑timers is a tiny utility library that provides safer, more ergonomic wrappers around JavaScript’s native timer functions (setTimeout, setInterval, setImmediate) and adds higher‑level patterns such as timeout‑based loops, dynamic‑adjusted loops, and exponential‑backoff calculations. It’s aimed at Node.js and browser developers who need reliable timer behavior—especially for long timeouts, cancellation, and precise scheduling—without dealing with the quirks of the built‑in APIs.
