The person sharing the information is definitely solid in the basics. The comments here and there were very helpful. But apart from that, the class was average. It was good to be able to feel the utility of React while reimplementing the functions implemented in Vanilla JS in React, but the class became too loose. And as it went on, I felt like the class lost its energy... I know that function compositors also use a hook called useState to manage state, but when you say that function compositors don't have states, it's a bit... subtle... I wish you had introduced the concept of hooks.
