The lecture structure is really good!! There are many parts where you can definitely feel the instructor's skills, and I think the casual comments will be very helpful in practice. The difficulty level is appropriate for a beginner's level compared to an introductory lecture, but I think even beginners will find it very helpful if they follow along well. I will definitely purchase the instructor's lecture if it comes out. Since the instructor has a lot of practical experience, I want to hear more in-depth content aimed at practical developers rather than beginners. I'm really enjoying the lecture. It's almost over, but I'm sad. I plan to listen to it from the beginning 2-3 more times.
