Как добавить функции к таймеру?

Question

[De Slow]

Помогите пожалуйста, как реализовать остановку таймера при 00-00, выводить другой текст вместо цифр, и когда таймер на нуле-открывать попап окно

Можно ли это реализовать с помощью: setTimeOut?

Сейчас таймер отображается в двух местах

window.onload = function () {
          startTimer(5, document.getElementById("time")); // 5 - сколько секунд ; document.getElementById("time") - блок, где нужно значение
          startTimer(10, document.getElementById("time1"));
      };


      function startTimer(duration, display) {
          var start = Date.now(),
              diff,
              minutes,
              seconds;
          function timer() {

              diff = duration - (((Date.now() - start) / 1000) | 0);

              minutes = (diff / 60) | 0;
              seconds = (diff % 60) | 0;

              minutes = minutes < 10 ? "0" + minutes : minutes;
              seconds = seconds < 10 ? "0" + seconds : seconds;

              if ( minutes === '00' && seconds === '00') {
                  display.textContent = 'текст'; // тут ваш текст
                  clearInterval(interval)
              } else {
                  display.textContent = minutes + ":" + seconds;
              }

              if (diff <= 0) {
                  start = Date.now() + 1000;
              }
          };
          var interval = setInterval(timer, 1000);
          timer();
      }
