如何使用多个异步/等待函数？

// 模拟异步操作
function delay(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

async function fetchUserData(userId) {
  await delay(1000);
  return { userId, name: 'John Doe', age: 30 };
}

async function fetchUserPosts(userId) {
  await delay(1500);
  return [
    { postId: 1, title: 'First Post' },
    { postId: 2, title: 'Second Post' }
  ];
}

async function getUserInfo(userId) {
  try {
    const userData = await fetchUserData(userId);
    const userPosts = await fetchUserPosts(userId);
    return { userData, userPosts };
  } catch (error) {
    console.error('Error fetching user info:', error);
    throw error;
  }
}

// 调用getUserInfo函数
getUserInfo(1)
  .then(info => console.log(info))
  .catch(error => console.error(error));

async function getUserInfoConcurrently(userId) {
  try {
    const [userData, userPosts] = await Promise.all([
      fetchUserData(userId),
      fetchUserPosts(userId)
    ]);
    return { userData, userPosts };
  } catch (error) {
    console.error('Error fetching user info:', error);
    throw error;
  }
}

// 调用getUserInfoConcurrently函数
getUserInfoConcurrently(1)
  .then(info => console.log(info))
  .catch(error => console.error(error));
