@hurtubisecarl put this one after my code:

function shuffleArray(array) {
    for (let i = array.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [array[i], array[j]] = [array[j], array[i]];
    }
return array;
}

after my code, and that’s all (shorter code than your shuffling function).
