如何从async/await函数返回值？

async function getData() {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      resolve('Data');
    }, 1000);
  });
}

async function main() {
  const result = await getData();
  console.log(result); // 输出：Data
}

main();

async function getData() {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      resolve('Data');
    }, 1000);
  });
}

async function main() {
  try {
    const result = await getData();
    console.log(result); // 输出：Data
  } catch (error) {
    console.error(error);
  }
}

main();

let globalData;

async function getData() {
  globalData = 'Data';
}

async function main() {
  await getData();
  console.log(globalData); // 输出：Data
}

main();
