I feel that while listening to the lecture, the value of this lecture is that it is good to teach technical contents such as next.js and antd, but the real value is that it is more useful to share the know-how that the lecturer learned from his work. In particular, the part where the lecturer conveys the mistakes that beginner front-end developers can make and the mistakes he made and the thoughts he felt from them will be more useful to beginner front-end developers who are listening to this lecture.
