In Part 1, I learned the basics of React, and in Part 2, I learned in depth about the structure of React, including hooks. To be honest, Part 2 was difficult... especially for a React beginner. I'm a complete React newbie and not very good at JavaScript, so there was a lot of code I didn't understand and I made a lot of mistakes. However, I think my coding skills have improved a lot in the process... (how to debug/how to structure) I'm grateful to the instructor for helping me improve, and I'll try to take other courses as well.
