sign up form usng React

This was a nice project, I'm very happy with the result, I managed to practice a lot of new things, including the use of Hooks,and How to Deploy React App to GitHub Pages,that was my first project.the problem that i faced is how to handle form inputs using React Hooks(useState),i was very confused about using one only state for all of the inputs or use one state for each input.

Feel free to suggest code improvements!
