Indentation is off.

Have you installed the prettier VSCode extension and enabled "Format on save/paste" on VSCode,
as recommended in https://github.com/CodeYourFuture/Module-Structuring-and-Testing-Data/blob/main/readme.md ?

If you have enabled "Format on save" but it is not working, it is likely that you haven't assign a formatter for JS file. This could happen if you have zero or multiple extensions that can format .js file.

If you have installed "Prettier" extension. To assign it as the formatter of JS code, you can try:

  1. Use "Format document" to format the JS file. Sometimes, VSCode will ask you to choose a formatter, and you can manually select "Prettier".
  2. Edit settings.json and set Prettier as the default formatter for JS.

Thank you. it seems it wasn't on. i've applied this now.

// Reset any existing timer first
resetTimer();

// Store the input as the remaining seconds to count down
remainingSeconds = seconds;

// Update display immediately
updateTimeDisplay();

// Start countdown
timerInterval = setInterval(() => {
remainingSeconds--;

updateTimeDisplay();

if (remainingSeconds <= 0) {
resetTimer();
updateTimeDisplay();
playAlarm();
}
}, 1000);
}

// Converts remainingSeconds into MM:SS format and updates the display
function updateTimeDisplay() {
const minutes = Math.floor(remainingSeconds / 60);

const seconds = remainingSeconds % 60;

const formattedMinutes = minutes.toString().padStart(2, "0");
const formattedSeconds = seconds.toString().padStart(2, "0");

const timeDisplay = document.getElementById("timeRemaining");
timeDisplay.textContent = `Time Remaining: ${formattedMinutes}:${formattedSeconds}`;
}
