自定义 hook - useLocalStorage

function useLocalStorage(key, initialValue) {  const [value, setValue] = useState(() => {    const storedValue = localStorage.getItem(key);    return storedValue !== null ? JSON.parse(storedValue) : initialValue;  });  const setLocalStorageValue = (newValue) => {    localStorage.setItem(key, JSON.stringify(newValue));    setValue(newValue);  };  return [value, setLocalStorageValue];}

优化点

1. JSON.parse 时支持报错，且 hook 支持 获取字符串
2. setLocalStorage 支持传入函数
