Appointment Planner challenge project

Hey, everyone. Still here on 45% of Full-Stack Career path.

Finished and deployed on Netlify challenge project Appointment Planner. Added some bootstrap. Have a look if you have time. And if someone can explain the part so in AppointmentForm.js instead of using handleSubmit with onSubmit in <Form> I used handleSubmit with onClick in <Button> and it worked.

Here is my appointment planner on Netlify https://transcendent-sorbet-2db90c.netlify.app/
