Launch Countdown TImer

What are you most proud of, and what would you do differently next time?

I am most proud of building a functional, accurate countdown timer using React and Tailwind CSS. My focus was on ensuring the time calculations (converting milliseconds into days, hours, minutes, and seconds) were robust and that the UI remained responsive on all screen sizes. Next time, I would like to experiment with CSS keyframes or a library like Framer Motion to add the "flip" card animations to match the design even more closely.

The main challenge was managing the setInterval logic within the React component lifecycle. I had to ensure that the interval was properly cleared when the component unmounted to prevent memory leaks. I overcame this by using the useEffect hook with a cleanup function.

What specific areas of your project would you like help with?

I would like feedback on the flip animation.
