I only learned Java grammar and then suddenly, unintentionally? I got a job. At first, I started without knowing what Spring was, controller? service? sql?? and I've been working in the wild for over a year unintentionally! ㅠ I happened to find this roadmap in the middle and I'm studying it one by one through the lectures. In fact, if you don't know anything, it's a big concern that you don't even know what to look for, but thanks to this series, I'm able to figure it out one by one. I really like how you always explain things step by step from the bottom! I'll listen to the rest of the lectures well. Thank you : )
