If you keep listening to good lectures, you will get used to good things. What if you can't watch other lectures? As you said, there was a time when I didn't know anything about Spring and was preparing a portfolio, but after listening to the lecture, I wonder how I made it... I also listened to a few JPA lectures, and I think your lecture skills are improving. It seems like you are telling me that I can grow if I keep listening to lectures as well as development, so I am more inspired. You are giving me good stimulation!ㅋㅋㅋ Thank you for the good lecture. I am looking forward to the DB lecture!
