I was able to understand the basic principles of HTTP web well! It was explained easily so I could understand the overall principles, and if there was something I needed, I also learned which keywords to search for to acquire the knowledge I wanted. I am trying to prepare for a career change while riding the wild roadmap in earnest, and it seems like I can build up my basic stamina, so it is good. It doesn't just write "Prerequisite knowledge: Basic knowledge of HTTP web" and end there, but it seems to say "You need basic knowledge of HTTP web as prerequisite knowledge, and I will teach you well." Thank you so much for making such a great lecture :) Question. I am preparing to switch to being a backend developer, and I wonder which roadmap is appropriate, the Spring roadmap or the Spring Boot + JPA roadmap.
