Basic Static Component using React with Vanilla CSS

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

First time using React, ever.

I'm proud I was able to store all of the list contents in an array of objects and then map through them to populate the <li> elements, essentially making a reusable list Component.

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

Nothing in particular.

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

I want help with making my Components more reusable. How would you go about splitting this project up into more separate components? I know the question is vague but I think I have too much hard-coded stuff and would like someone who is more experienced than me with React to give some insight into how they would approach this project using React.

(Also I know I have all of my components in 1 file and should split them into separate files, but since it is a very small project I just left them all in the app.jsx)
