如何在promise.all中进行异步等待

const promise1 = new Promise((resolve, reject) => {
  setTimeout(() => {
    resolve('Promise 1 resolved');
  }, 2000);
});

const promise2 = new Promise((resolve, reject) => {
  setTimeout(() => {
    resolve('Promise 2 resolved');
  }, 3000);
});

const promise3 = new Promise((resolve, reject) => {
  setTimeout(() => {
    resolve('Promise 3 resolved');
  }, 1500);
});

Promise.all([promise1, promise2, promise3])
  .then((results) => {
    console.log(results); // 输出: ["Promise 1 resolved", "Promise 2 resolved", "Promise 3 resolved"]
    // 在这里可以对结果进行进一步处理
  })
  .catch((error) => {
    console.log(error); // 如果任何一个Promise被reject，则会输出对应的错误信息
  });
