I finished the minimum requirements for learning Spring and finally, though late, I'm learning Spring!!! If I had tried to do Java and Spring by myself, it would have felt overwhelming, but thanks to Younghan, I feel like I gained the courage to start Spring. Thank you always for the great lectures. I'm listening diligently, so please continue to help me fill my knowledge in the future!!! 😊😊
