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

Method for selecting the tip rate, with useState and onClick action.

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

Entering data into a type="number" input field can be uncomfortable in a mobile phone, due to lack of delete key.
