Ecommerce product page build with React

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

I used to use Redux for managing complex states in react apps. But this time I tried the useContext hook for cart states. I wanted to practice it more and compare it with Redux. Wait, am I really proud with it? Guess should be something.

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

I decided to bring this project closer to the real one. To do this I put the product data to a separate file and tried to build app as if there could be more products. Also I slightly changed "add to cart" design for more deep work with context. Well, after I made those challenges up, I successfully overcame them.

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

As always I'll be more than happy to receive some critics, advices and just random comments =)
