Product list with Cart using a JSON data file

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

In a past project I tried to use a data.json file provided by frontendmentor to populate information dynamically, but it doesn't work. Now I know that it is necessary to use live server in development to display that information. It was much better that way.

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

Any feedback would be fine :)
