I gave up studying Spring on my own because it was too difficult, but I wonder why I gave up on something so easy. I think the lectures are so good! I gave up studying Spring on my own and studied Node-based Nestjs, and while studying to get a taste of Spring's concepts, I also did some practical work. Now that I've done some practical work with NestJS, I understand how the concepts in Spring and NestJS work and why they exist! 3 hours passed by so quickly.
