Country browsing page with React Router

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

I haven't made many projects using APIs until now, so it was pretty intimidating, but that's how you learn new things, isn't it? I learned more about using fetch and async functions, and other stuff like "Promise.all()" and using React Router redirects. There are definetly a lot more things that I learn that I can't list here, but overall, this was a very educational project for me.
