Shouldn't this function, resetAlarm() be called in setAlarm()?

You should also reset the audio because the user may not click the Stop button before starting a new countdown.

Implemented. Thank you for your time!


function setAlarm() {
let seconds = parseInt(document.getElementById("alarmSet").value);

if (!seconds || seconds < 1) {
alert("The number of seconds must be more than 0 please");
return;
}
function updateDisplay() {
const minutes = Math.floor(seconds / 60);
const remainingSeconds = seconds % 60;
document.getElementById("timeRemaining").textContent =
`Time Remaining: ${String(minutes).padStart(2, "0")}:${String(remainingSeconds).padStart(2, "0")}`;
}

Oh no! Have I been careless cleaning up the pause button issue? Not the first time I've confused the script term "pause alarm" vs. the human term "stop alarm", apologies!
