As always, I trust and watch Younghan's lectures!!! I'm studying from JPA, Spring, and now Java from the basics to the intermediate level. I think the best advantage of Younghan's lectures is that I can learn deeply because I can learn why this technology is used from the beginning!! Please continue to give me better lectures so that you can become the bible of my development life!!! Younghan's lectures are so great because I can watch them once and watch them again without getting tired and actually learn more! Always stay healthy and I'll look forward to the next lecture!!! Thank you.
