赋值依赖于多个承诺的完成情况

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');
  }, 1000);
});

Promise.all([promise1, promise2, promise3])
  .then((results) => {
    const [result1, result2, result3] = results;
    const combinedResult = result1 + ', ' + result2 + ', ' + result3;
    console.log(combinedResult);
  })
  .catch((error) => {
    console.error('Error:', error);
  });
