Promise.all(), Promise.race(), and Promise.any()

What common use case does Promise.race() solve here?

async function timeout(promise, ms) {
  return Promise.race([
    promise,
    new Promise((_, reject) =>
      setTimeout(() => reject(new Error('Timeout')), ms)
    )
  ]);
}

Error handling
Timeout implementation
This implements timeout pattern with Promise.race(): 1) Races between actual operation and timeout, 2) Rejects if operation takes too long, 3) Returns result if operation completes in time, 4) Common pattern for preventing hanging operations, 5) Useful for network requests and long-running tasks, 6) Note that original promise continues running in background.
