REST Countries - REACT/REDUX/STYLED-COMPONENTS

Hello everyone ! 🙂

Here is my version of this challenge, any feedback/remark is appreciated ! I guess it would be better to load countries while scrolling ? But I wonder what might be the best direction to achieve this. Also the theme switcher is a bit laggy when there are all countries displayed, but it's smoother if I filter by region, so it's because the height is massive right ?

Have a nice day ☀️
