I cant get the localStoarge data, i'm using useEffect Hook - reactjs

Question

Every Time i try to refresh the page it returns to 0.
I'm taking the bestScore from turns when the match is equal to 6,
so basically everytime the matched cards hit 6 it will take the bestScore from the turns and save the bestScore to localStoarge and it works but when i try to refresh its gone
function App() {
const [cards, setCards] = useState([]);
const [turns, setTurns] = useState(0);
const [match, matchedCards] = useState(0);
const [bestScore, setBestScore] = useState(
localStorage.getItem("highestScoresss")
);
const [choiceOne, setChoiceOne] = useState(null); //Kullanici 1.karta basinca setChoiceOne o karti alacak ve guncelliyecek
const [choiceTwo, setChoiceTwo] = useState(null); //Kullanici 2.karta basinca setChoiceTwo o karti alacak ve guncelliyecek
const [disabled, setDisabled] = useState(false);
useEffect(() => {
if (match === 6) {
const highScore = Math.min(turns, bestScore);
setBestScore(highScore);
setBestScore(turns);
} else {
console.log("false");
}
}, [turns]);
useEffect(() => {
localStorage.setItem("highestScoresss", JSON.stringify(bestScore));
});
This Is the JSX
<div className="bilgi">
<p>Sıra: {turns}</p>
<p>Bulunan: {match}</p>
<p>En iyi Skor: {bestScore}</p>
<button onClick={shuffleCards}>Yeni Oyun</button>
</div>
</div>

Answer 1

The issue with your implementation is that you set state to 0 first, and then the useEffect hook runs and sets localStorage to the state value.
If you are potentially initializing your state to a value stored in localStorage then I suggest using a lazy initialization function so the initial state value is set before the initial render and eliminates the need for the additional useEffect hook to set state from storage. This reads from localStorage and returns the parsed value, or 0 if the parsed result is null or undefined.
const initializeState = () => {
return JSON.parse(localStorage.getItem("highestScoresss")) ?? 0;
};
...
const [bestScore, setBestScore] = useState(initializeState());
You will want to use a dependency array on the useEffect that is persisting the "highestScoresss" value in localStorage such that it only triggers when the bestScore state value updates and not on each and every render.
useEffect(() => {
localStorage.setItem("highestScoresss", JSON.stringify(bestScore));
}, [bestScore]);

Answer 2

After looking at the Code image, I think that you want that the bestScore to be set in the local storage with the key highestScores.
Your current useEffect hook implementation lacks a dependency array. You want that the localStorage should be updated every time a new bestScore is set.
For that add bestScore to the dependency array.
useEffect(() => /* YOUR OPERATION*/, [any_dependency])
Also, I recommend that you look at your first useEffect implementation again. You seem to be setting the bestScore state twice. Once with highScore and then with turns.
