Before taking the class, I only knew the basic flow of Spring while working on a toy project, but through the class, I feel like it gradually fills in the empty foundation of how it is used in the field, what happens in the Spring container, dependency injection with @Autowired, commonly used shortcuts, etc. I love it!!!!! This is a free lecture... I'm surprised ㅠㅠ There's really no part to waste, not even one second. I've only listened to half of it, but I'm going to listen to the rest and follow Younghan's roadmap!! It's been a long time since I've seen someone with both skills and teaching ability, so I'm so excited. I'll definitely finish it!!!!! Thank you ㅎㅎ Fighting!!~
