It really feels like the basics are becoming solid. At first, when I listened to the intro lectures, I thought Spring was a bit difficult, but after listening to that lecture and starting the course with the basic core principles, the more I listened, the more it stuck in my head. At first, there was only the Spring interface, but the implementations were created one by one and assembled! It flows exactly as expected, and as I review, it sticks in my memory. ㅎㅎ I think I made a good choice. After work, I really think about watching the lecture without MSG and leave work feeling excited. ㅋㅋㅋ
