Hello, Younghan! It was very helpful! I think I understood better because I was able to study from the background! I am currently taking the 3rd Backend course of the Elegant Tech Course, and I had to give a presentation on Spring and Spring Boot at TechTalk a while ago. This lecture was really helpful at that time! Also, I was busy with the mission, so I only finished the latter half of the lecture after vacation, but there are many functions that I think would be good to apply to the mission. I really want to apply what I learned this time to the project. Thank you so much for the helpful lecture! I will go listen to the next lecture right away! 🙏
