Hello, Mr. Kim Young-han. I am a junior developer who has been wandering around after only working on Spring Legacy projects, feeling like I will be left behind by the times and that no one will come to me, so I took nodeJS lectures and reactJS lectures. However, since I have been learning and using Spring as my main focus, I have returned to Spring like a salmon. This lecture is a very valuable lecture that has calmed my anxious mind. Even when I tried to learn Spring Boot, the version was updated too quickly, so it was not easy, but thanks to the detailed information provided through the materials, I was able to complete the course safely. It was great that I was even able to learn JPA, and it was much easier to understand because the concepts that could be easily missed were explained well and emphasized separately. The roadmap is not finished yet, so I will take the lecture again, but I would like to say that I am truly grateful for the knowledge sharing that is full of soul, and I hope that others who take this lecture will also make a choice without regrets, and I hope that you will complete the course and succeed. Thank you.
