Pros: A brief why is attached to the explanation of all codes, file packages, etc. Editing is also neat for me High level for beginners Content is rich In a short time, in one lecture, the payment domain is explained and implemented by only pointing out the key points Reference before taking the course: The domain itself is difficult, so it is beginner level, but the content is not beginner level Editing will be a matter of preference. It is neatly edited, so the audio does not cut out well in the middle = the lecture is fast If you know at least hexagonal architecture or clean-DDD, it will be easy to follow the lecture Beginners who are not proficient in MVC are expected to have a hard time progressing when they encounter reactive.
