how to export timeOut variable in JS

I'm making a Js memory game using express and mongoose

  function incrementAttempts(){
        attempts++;
        attemptsHolder.textContent = attempts;
       
        }


// Function to check if the chosen cards match
    function checkForMatch() {
        const [card1, card2] = chosenCards;
        const [cardId1, cardId2] = chosenCardsIds;

        // If the cards match, update foundCards count and display
        if (card1 === card2) {
            foundCards += 2;
            foundHolder.textContent = foundCards;
            if (foundCards === cardsInGame) {
                // const final = attempts;
                setTimeout(()=>{
                    console.log(attempts);
                    alert(`Congratulations! You found all the pairs in ${attempts} attempts.`);
                },0);
         
            }
        } else {
            // If the cards don't match, flip them back
            document.querySelector(`[data-id="${cardId1}"]`).textContent = '';
            document.querySelector(`[data-id="${cardId2}"]`).textContent = '';
        }

        // Clear the chosen cards arrays
        chosenCards = [];
        chosenCardsIds = [];

        // Increase attempts count and display
      incrementAttempts()
    }

  function incrementAttempts(){
        attempts++;
        attemptsHolder.textContent = attempts;
       
        }


// Function to check if the chosen cards match
    function checkForMatch() {
        const [card1, card2] = chosenCards;
        const [cardId1, cardId2] = chosenCardsIds;

        // If the cards match, update foundCards count and display
        if (card1 === card2) {
            foundCards += 2;
            foundHolder.textContent = foundCards;
            if (foundCards === cardsInGame) {
                // const final = attempts;
                setTimeout(()=>{
                    console.log(attempts);
                    alert(`Congratulations! You found all the pairs in ${attempts} attempts.`);
                },0);
         
            }
        } else {
            // If the cards don't match, flip them back
            document.querySelector(`[data-id="${cardId1}"]`).textContent = '';
            document.querySelector(`[data-id="${cardId2}"]`).textContent = '';
        }

        // Clear the chosen cards arrays
        chosenCards = [];
        chosenCardsIds = [];

        // Increase attempts count and display
      incrementAttempts()
    }

i want to get hold of the attempts variable in setTimout alert. Can i export it into another js file?? Beacuse mainly i want to push that attempts variable in MonogoDB

You could pass a callback into checkForMatch like:

function checkForMatch({ onMatch }) {
  ⋮
  if(card1 === card2) {
    onMatch({ attempts })
    ⋮

function checkForMatch({ onMatch }) {
  ⋮
  if(card1 === card2) {
    onMatch({ attempts })
    ⋮

Though if you're wanting the value to write it to Mongo, why not just write it where the match is found?

you could return the current attempts number from the incrementAttempts() after you incremented it and call that as the first line in checkForMatch(), stored in a variable

function incrementAttempts(){
  attempts++;
  attemptsHolder.textContent = attempts;
  return attempts;       
}

// Function to check if the chosen cards match
function checkForMatch() {
  const [card1, card2] = chosenCards;
  const [cardId1, cardId2] = chosenCardsIds;
  const attempts = incrementAttempts();
  // If the cards match, update foundCards count and display
  ⋮
}

function incrementAttempts(){
  attempts++;
  attemptsHolder.textContent = attempts;
  return attempts;       
}

// Function to check if the chosen cards match
function checkForMatch() {
  const [card1, card2] = chosenCards;
  const [cardId1, cardId2] = chosenCardsIds;
  const attempts = incrementAttempts();
  // If the cards match, update foundCards count and display
  ⋮
}
