sleep, timeout, eventually and throttle accept { signal } (see the repository README, "Cancellation"): aborting clears the pending timer and rejects with signal.reason; eventually stops retrying and throttle drops its pending trailing call. An attempt or f already in flight is left to settle on its own.
const controller = new AbortController()
setTimeout(() => controller.abort(), 100)
await F.sleep(10_000, { signal: controller.signal }) // rejects after 100 ms with signal.reason
await F.eventually(() => fetch(url, { signal: controller.signal }).then(r => r.ok), { delay: 500, signal: controller.signal })
