从syncExec返回变量的最佳方法是什么？

async function getSyncExecResult() {
  const result = await syncExec();
  console.log(result);
}

function getSyncExecResult(callback) {
  syncExec().then((result) => {
    callback(result);
  });
}

async function getSyncExecResult() {
  try {
    const result = await syncExec();
    console.log(result);
  } catch (error) {
    console.error(error);
  }
}

function getSyncExecResult(callback) {
  syncExec().then((result) => {
    callback(null, result);
  }).catch((error) => {
    callback(error);
  });
}
