Mortgage repayment calculator using React

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

I liked how the solution turned out. The form validation is nice. I tested it with letters, numbers, and '500-' and it showed the correct error messages.

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

I had a hard time with the form validation, searched a lot on Youtube and AI.

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

I used Lighthouse on DevTools to make improvements on the project, is it a good tool?

I didn't like building this project, especially the form validation, I need to practice some more, anyone know a good course? I'm very interested.

Accessibility report on Lighthouse was 100%, is it correct or should I change something?
