Why I recommend this course 1. Perfect lecture flow: Problems before JPA -> Introduction to JPA -> Explanation of concepts, principles, and live coding -> Real-life examples (toy projects) The lecture explains in live coding what functions should be used in what situations, why they should be used, how they should be used, and what the principles are. Thanks to this lecture method, I was able to understand better and remember them for a long time. I think it is a great advantage that you can feel the overall flow as well as how to use each function through real-life examples. (Especially for beginners) 2. Clean lecture materials The concepts, tips, and codes introduced in the lecture are all neatly organized in the lecture materials, making it very convenient to review. Usually, when I take a lecture at university, I would write down everything the professor said so that I wouldn't miss anything, but I would often end up focusing on writing down everything rather than understanding it. (When the professor spoke too fast or had a bad pronunciation, I would cry..) In this lecture, everything that was taught in the lecture was neatly organized in the lecture materials, so I could focus only on the lecture content, and I think it's a big advantage that the instructor's pronunciation, speed, and tone were all perfect. 3. Same-day feedback When you don't know something, don't understand it well, or want practical advice, if you post a question on the Q&A board, the instructor will reply to you directly after work on the same day, and share many useful postings. In particular, I think it's rare to have a lecture where you can even run a supporter group and have many people reply to your comments. There are so many questions and answers, and I learned a lot not only from the lecture but also from reading the Q&A about things I was curious about or hadn't thought about. I think this is a really good lecture for beginners to build basic knowledge, and it also teaches a lot of practical things, so I think it will be a great help to those in the field! Since it is a lecture filled with only the contents that are really necessary, you can see that it saves a lot of time! p.s) Thank you, instructor, for always making great lectures😊 Finally, only querydsl is left until the roadmap is complete..! Thanks to the instructor's lecture, I was able to study happily, and it was really helpful!
