The Spring Advanced version was really fun. Because it was structured in Mr. Kim Young-han's unique storytelling style, I was able to approach the difficult content with enjoyment. When I listened to the previous lecture, I had no idea what a proxy was, but now I can remember its role and structure, which is good. I'm listening to the JPA lecture now, and I'm actually really surprised. Maybe it's because it was filmed early on, or because it was dark and he was always busy with work, but the atmosphere was really different. Hahaha. I didn't know because he was always smiling and had a high tone. Anyway, I'll enjoy the other lectures too (_ _)
