Retry Until Predicate

Implement retryUntil(fn, predicate, maxAttempts, delay) that keeps calling fn until the predicate is satisfied or attempts are exhausted.

Requirements

• Call fn() and check the result against predicate(result).
• If the predicate returns true, resolve with the result.
• If maxAttempts is exceeded, reject with "Max attempts reached".
• Wait delay ms between each attempt.
• If fn throws, count it as a failed attempt and continue retrying.

Example

let count = 0;
const result = await retryUntil(
  () => ++count,
  (n) => n >= 3,
  5,
  10
);
// result === 3
