REST Countries API with color theme switcher

Hey wevs

Happy to see you finished this challenge, great work. I'd like to give some feedback after review your code.. hope it would be helpful

First of all, From App.js I'd like to recommend you read the react documentation of how to use useState hook. it should be const [a, setA] format, T is too ambiguous and hard to understand the actual meaning, and you can name it from togglerFunc to toggleTheme to match. Secondly, in Navbar.js, you can try to encapsulate those two components in different conditions to make your code easier to read.. Moreover, In CountriesPage, you can chain your fetch function with then make your response to be json format, and you can refactor it to not call api when its already loaded once (store data in local storage for example).. I saw you have commented eslint lines, you can configure them in eslint configure file and loading === false can be refactored to !loading, same for error.. In CountryDetailPage, you can rename cd to CountryDetails to make it more descriptive and then extract those properties out by doing .then({subregion, capital}) for example..

Generally speaking, really good project, achieved core functionality, used several hooks to make it easier to build.. Hope everything makes sense and can be helpful
