Notes:

  • Could probably just check both conditions in the one if-statement and then change the message to mention "... positive integer".

  • While alert() is convenient to use, it is not a user-friendly way to notify the user an error.

No change needed.

yes i made changes but it is still showing to do list I have replaced the orignial file and pushed it through, but I think I have made both under sprint 3 so thats why its showing like this. any idea how can i sort it out usually when I replace the original file from github it goes away but this time it didnt. May be becuase they both in sprint 3. Are you able to help otherwise its failing the checks


let timeRemaining = numberValue;

function formatTime(totalSeconds) {
const minutes = Math.floor(totalSeconds / 60);
const seconds = totalSeconds % 60;

return `Time Remaining: ${String(minutes).padStart(2, "0")}:${String(
seconds
).padStart(2, "0")}`;
}

// Show starting time
heading.innerText = formatTime(timeRemaining);

document.getElementById("stop").addEventListener("click", () => {
pauseAlarm();
});
// Stop an existing timer
clearInterval(timer);
pauseAlarm();

timeRemaining = 0;

// Play alarm
function playAlarm() {
audio.play();

// Stop alarm

audio.currentTime = 0;

// Setup buttons
