It seems very easy to listen to because you explain it with code compared to pure JPA~ There are many unfamiliar parts now, but I'm watching it while following along to the point that I know there's such content.^^ I always study through Younghan's lectures and I've really received a lot of help, and I'm applying the information and knowledge I've gained to areas I was concerned about while working on the final boot camp project and to improving performance. Thank you^^
