I wanted to watch MVC2 first, but.. I think I'll be able to understand it properly if I follow the roadmap, so I listened to the previous lectures diligently with the mindset of gathering energy, and now I can study error page processing and ExceptionHandler in detail, which I was really curious about!! I haven't finished the course yet and I'm writing a review, but I listened to it with the mindset of reviewing what I've already heard to organize the concepts about sessions and cookies, so it was a lot easierㅎㅎㅎ I really trust Younghan's lecturesㅠㅠㅠ It's much easier to understand when I understand it while doing live coding As Younghan said, I think developers have to code to understand it easilyㅋㅋ I'll watch the remaining videos diligently!
