const [ratings, setRatings] = useState([]);

const ratingHandler = (value) => {
    // Create a copy of the ratings array
    let newArray = [...ratings];
    const index = newArray.indexOf(value);
    if (index !== -1) {
        // Item exists, remove it
        newArray.splice(index, 1);
    } else {
        // Item doesn't exist, add it
        newArray.push(value);
    }
    // Update state with the new array
