ReactJs, Mobile First Solution, PWA Support

I started learning ReactJs 5 days ago and decided to use it in this challenge, when i was far ahead into this project i learned about other hooks like useEffect and useRef but didn't wanted to go back and change the code because this project was taking already more time than i really wanted it to take. Took me around 10h to complete this challenge in a span of 5 days. I'm new to web development so any feedback is greatly apreciated!
