Hi 👋

I’ve submitted my PR for Sprint 3 – Alarm Clock App and it has been in Needs Review for more than 2 weeks.

Because it wasn’t reviewed in time, my module submission was marked as incomplete.

I would really appreciate it if someone could review my PR so I can address any feedback and resubmit as soon as possible.

🔗 PR: #1096

Please let me know if anything specific needs to be improved.

Thank you for your support 🙏 @jayshreehajgude2012

Good use of setInterval like inbuilt functions and DOM methods.
Nice formatTime() function with padStart() to make code clean.
Efforts put to Separate formatting logic from update logic.
