The biggest advantage of Zerocho's course is that he explains the know-how he acquired while developing in the field. As you can see from other Zerocho's courses, you can feel that he chose the target to clone very carefully. Since Nest.js is a course that was filmed a while ago, Zerocho's teaching skills are a bit lacking compared to recent courses, but if you implement it yourself based on the course and ask Zerocho questions directly, I think it is a really good course that you will not regret the price! I feel good about completing the course that I bought and put off while doing Time Attack! I really recommend Time Attack!
