How would I write these codes using for Loop instead of forEach?

JavaScript
1

Code 1.)

    function pauseAllButtons() {
      const buttons = document.querySelectorAll(".playButton");
      buttons.forEach(function hidePause(button) {
        if (isPlaying(button)) {
          showPlayButton(button);
        }
      });
    }

Code 2.)

    function hideAllButtons(button) {
      button.querySelectorAll(".play, .pause, .speaker").forEach(hide);
    }
