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

I'm proud that I learned several processes during this project.

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

I'm still learning JavaScript and programming logic, so I had the opportunity to use this ability that I'm still developing through this project.

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

I'd like to have feedback about the structure that I used to make this project, I'm still learning JavaScript and I decided to use React, I appreciate it if someone sees my code and gives feedback about it.
