I am a job seeker who studied only Java grammar and watched all of Younghan's lectures in the order of JPA -> Spring roadmap. (I think the order changed, but when I started, there was only the Spring basics ㅠㅠ) I think I was able to get here without much difficulty because he explained in an easy way that even I, a beginner in programming, could understand what problems ancient developers felt and how they developed. I think it was because I had listened to the advanced lecture before, so when concepts like templates, callbacks, proxies, and AOP came out, I found them interesting and thought that they were used in this way. Later, when I was creating a function, I thought that I should introduce patterns when I had repetitive code or dependency problems. If I had started with a book like Projects with Spring, I might have been satisfied with just using Spring, so I think it was a good decision to start with Younghan's lecture :) As you said while waiting for DB Part 2, I am trying to move beyond the study stage to the acquisition stage, but I don't know where to start, but I plan to follow Younghan's advice and create small projects step by step. Of course the lecture is good, but I think the direction you give me at the end is a great motivation for me. Thank you so much^^
