import { useCallback, useEffect, useState } from "react";
export const useLocalStorage = (key, initialValue) => {
const initialize = (key) => {
try {
const item = localStorage.getItem(key);
if (item && item !== "undefined") {
return JSON.parse(item);
}
localStorage.setItem(key, JSON.stringify(initialValue));
return initialValue;
} catch {
return initialValue;
}

const [state, setState] = useState(null); // problem is here
// solution is here....
useEffect(()=>{
setState(initialize(key));
},[]);
const setValue = useCallback(
(value) => {
try {
const valueToStore = value instanceof Function ? value(storedValue) : value;
setState(valueToStore);
localStorage.setItem(key, JSON.stringify(valueToStore));
} catch (error) {
console.log(error);
}
},
[key, setState]
);
const remove = useCallback(() => {
try {
localStorage.removeItem(key);
} catch {
