The lecture itself doesn't have a complete Gateway feel, but I think it's great for beginners to learn. In fact, I didn't even know what the Gateway pattern was, so it was really helpful, and as I worked on the code together and saw the code being modified, it felt practical and very raw. I think this part of the lecture is not very well-structured and is more like a rough version, but I liked that it conveyed what he wanted to show. Thank you for the great lecture.
