REST Countries API with color theme switcher solution

When I started this challenge I was a little doubtful of this belonging to the 'Advanced' category. I thought it was pretty simple, and maaaaan I wrong lol.

This exercise challenged me a lot, and for the first time I noticed the advantages of working with TypeScript. Although, the development of this project was a slow in order to meet TypeScript requirements, at the moment of refactoring the code TypeScript shined and made me avoid big mistakes.

Unfortunately I worked from beginning to end with the mockup data provided in the challenge started pack. And I did not notice that the API end-point changed its structure; thus I could not integrate the API to my project. Though I could have fixed it, since I made the API call and got all the countries, I did not consider I could learn something new by refactoring that part of the code. Therefore, I left it like that and commented the fetching data part.
