The classes are fun and good, but too many explanations are skipped on the frontend side. Since the instructor just types the code quickly, I end up just copying it without knowing the reason why. It feels like the videos weren't planned with a pre-determined structure or reasoning, but rather composed on the fly; the code keeps changing back and forth, and since there are no separate explanations for those changes, it was very frustrating while building the views... Because of this, I think it will be difficult for beginners like me who are new to React to understand.
