是否将此基于Promise的代码转换为异步/等待？

// 原始基于Promise的代码
function fetchData() {
  return new Promise((resolve, reject) => {
    // 异步操作
    setTimeout(() => {
      resolve('Data fetched successfully');
    }, 2000);
  });
}

function processData(data) {
  return new Promise((resolve, reject) => {
    // 异步操作
    setTimeout(() => {
      resolve('Data processed: ' + data);
    }, 2000);
  });
}

fetchData()
  .then(data => processData(data))
  .then(result => {
    console.log(result);
  })
  .catch(error => {
    console.error(error);
  });

// 转换为异步/等待的代码
async function fetchData() {
  return new Promise((resolve, reject) => {
    // 异步操作
    setTimeout(() => {
      resolve('Data fetched successfully');
    }, 2000);
  });
}

async function processData(data) {
  return new Promise((resolve, reject) => {
    // 异步操作
    setTimeout(() => {
      resolve('Data processed: ' + data);
    }, 2000);
  });
}

async function main() {
  try {
    const data = await fetchData();
    const result = await processData(data);
    console.log(result);
  } catch (error) {
    console.error(error);
  }
}

main();
