I finally finished reading the lecture. I think I always had doubts about "Is my code really good code?" while developing in the field. This lecture is a great lecture that helped me resolve many of those doubts. (Why didn't you release the lecture earlier ㅠㅠ ㅋㅋ) I heard that you had racked your brains preparing for this lecture in the last section of the lecture, and I had to admit that it was a really informative lecture for me. I'm looking forward to the next lecture!
