用async/await实现

以下是使用async/await实现的例子：

async function asyncPromiseAll(arr) {
  let result = [];
  try {
    for (let i = 0; i < arr.length; i++) {
      let h = await arr[i];
      result.push(h);
    }
  } catch (err) {
    // 错误处理
  }
  return result;
}

// 示例用法
let promises = [Promise.resolve(1), Promise.reject(), Promise.resolve(3)];
asyncPromiseAll(promises).then(res => {
  console.log(res); // [1, undefined, 3]
});
