Last year around this time, I first listened to Younghan's lecture and thought, "So this is what Spring is like," and since then, for school projects and toy projects, I used PHP in the past, but after listening to the lecture, I used Spring for projects. After doing several projects, I took the lecture again this time to review the basics of Spring, and it was a lecture that was as informative and fun to listen to again. I think the basic lecture is the most recommended lecture for those who want to build a solid foundation in Spring!! Thank you for making such a great lecture!!
