While studying development, I wondered if this was the right way to study. Is it right to just learn grammar and move on? I searched for good lectures while worrying about this. After listening to the basic and intermediate 1 lectures, I realized that this was the lecture I was looking for. Somehow, I didn't feel like I was studying properly while studying backend, but when I listened to instructor Kim Young-han's lectures, I felt like I was really studying properly. I want to finish the intermediate 2 lectures, Spring, Spring Boot Roadmap, and the advanced and database roadmap that will come out later.
