当前每个值都是在设置前一个值之后设置的，异步调用不会并行执行。如何使这些调用并行执行？

  const [index, setIndex] = useState(0);
  const [roll, setRollNo] = useState(1);
  const [sem, setSemester] = useState(1);

  useEffect(() => {
    getMyValue();
  }, []);

  const getMyValue = async () => {
    try {
      setIndex(JSON.parse(await AsyncStorage.getItem('@branch')) || 0);
      setSemester(JSON.parse(await AsyncStorage.getItem('@sem')) || 1);
      setRollNo(JSON.parse(await AsyncStorage.getItem('@roll')) || 1);
    } catch (e) {
      //  console.log(e);
    }
  };
