The lecture is really good. I took the course with only a little bit of nest.js knowledge, but I was able to follow along without much difficulty. However, I have a hard time acquiring a little more in-depth knowledge. I registered for the course because there was a section on typeorm (especially querybuilder) in the intermediate or higher level course, but I feel like I just skimmed through it. I wish the lectures were a little more detailed and in-depth for the intermediate level course.^^ However, it is true that it is a good lecture that can be of great help to beginners who have passed the introductory level.
