The parseInt function doesn't need the second param to be specfied for this use case - have a look at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/parseInt to find out why


if (isNaN(timeInSeconds) || timeInSeconds <= 0) {
alert("Please enter a valid positive number for the alarm time.");
return;

Good touch

}

let minutes = Math.floor(timeInSeconds / 60);
let seconds = timeInSeconds % 60;

countdown = setInterval(() => {
seconds--;

This line causes a bug - the seconds go down to -1 and when you add an alarm, the time is the time you entered -1. Can you see why this happens?


if (seconds < 0) {
if (minutes === 0) {
clearInterval(countdown);
playAlarm();
document.body.style.backgroundColor = "red"; // This was just optional, background color will change

Nice :)

You shouldn't change tests to make your code pass them - tests are there to tell you when things are wrong so you can fix them.
