使Promise.race仅在一次成功时结束

function racePromises(promises) {
  const racePromise = new Promise((resolve, reject) => {});
  const resolved = false;
  const resolvedHandler = (value) => {
    if (!resolved) {
      resolved = true;
      resolve(value);
    }
  };
  const rejectedHandler = (reason) => {
    if (!resolved) {
      resolved = true;
      reject(reason);
    }
  };

  const promisesArray = promises.map((promise) => {
    promise.then(resolvedHandler).catch(rejectedHandler);
    return promise;
  });

  return racePromise;
}

// 使用示例
const promise1 = new Promise((resolve) => setTimeout(resolve, 1000, 'Promise 1 resolved'));
const promise2 = new Promise((resolve) => setTimeout(resolve, 2000, 'Promise 2 resolved'));
const promise3 = new Promise((resolve) => setTimeout(resolve, 3000, 'Promise 3 resolved'));

const promises = [promise1, promise2, promise3];

const racePromise = racePromises(promises);

racePromise.then((value) => {
  console.log('Race promise resolved:', value);
}).catch((reason) => {
  console.log('Race promise rejected:', reason);
});
