JavaScript MVC Architecture, Responsive landing page using CSS grid

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

I use the MVC architecture in JavaScript, utilize the LocalStorage API to store data, implement light and dark modes, and enable the reordering of to-do lists using drag and drop.

What challenges did you encounter, and how did you overcome them?

saving the order of to-do lists when you dragged and dropped from downside to up when a refresh happened was challenging, and I tried a lot to overcome them.

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

I appreciate who can look into my JavaScript codes and let me know what part I could to better and I am looking forward to seeing your comments about my solution.
