Full Stack Todo App

After a couple of months of playing with React, this is my first project using it. I picked this challenge because I think this is a very good project to familiarize myself with the basics and react hooks. I also try how backend works so I use Firebase real-time database to save the tasks. I didn't add the drag and drop feature for now because I can't find a way to reorder data from the server without deleting the entire set of data and just re-uploading the updated set of data. If someday I find a solution to this, I'll add it to this project. And for styling, I use styled-components because I'm not a fan of CSS-in-JS or CSS modules.

If you have any suggestion/feedback on how I can improve and reduce unnecessary code, please don't hesitate to comment. Thanks.
