I would like this function below to be running throughout the game, so when a player has no people left it will declare the winner. Is there a way to do this?

async function checkWinner() {
    if (document.getElementById('player1').innerText === '0') {
        message.innerHTML = `<p>${players[1]} you have won the game</p>`;
        await sleep(3000);
        window.location.reload();
    }
    if (document.getElementById('player2').innerText === '0') {
        message.innerHTML = `<p>${players[0]} you have won the game</p>`;
        await sleep(3000);
        window.location.reload();
    }

}

>Solution :

setInterval(async () => {
  await myAsyncFunction();
}, 1000); // Runs myAsyncFunction() every second

In this example, we pass an anonymous async function to setInterval(). Inside the function, we call myAsyncFunction() using the await keyword to wait for it to complete before moving on to the next interval.

Keep in mind that if myAsyncFunction() takes longer than the interval you specified, multiple invocations of the function may run concurrently, which could lead to unexpected behavior. To prevent this, you can use a locking mechanism such as a mutex to ensure that only one invocation of the function is running at a time.

Also note that using setInterval() with an asynchronous function may not be the most efficient way to accomplish your task, especially if the function takes a long time to complete or if you need to handle errors. In such cases, you may want to consider using a more robust scheduling library such as node-cron or agenda
