如何在Javascript的猜谜游戏中设置计时器？

<div id="timer">00:00</div>

var seconds = 0;
var timerInterval;

function startTimer() {
  timerInterval = setInterval(updateTimer, 1000);
}

function updateTimer() {
  seconds++;
  var minutes = Math.floor(seconds / 60);
  var remainingSeconds = seconds % 60;
  var formattedTime = padNumber(minutes) + ":" + padNumber(remainingSeconds);
  document.getElementById("timer").textContent = formattedTime;
}

function padNumber(number) {
  return (number < 10 ? "0" : "") + number;
}

startTimer();
