Promise.race

Get the first settled promise

Promise.race() returns the first promise to settle, whether it fulfills or rejects.

Promise.race([
  fetchFromServer1(),
  fetchFromServer2()
]).then(result => {
  // First response wins
});

Useful for timeouts: race your operation against a timeout promise.
