Advantages of this course: It's not a lecture for the sake of lecturing. It only teaches the skills needed for practical work. It feels more like a developer actively working in the field rather than just an instructor. It points you toward Prisma over TypeORM, Redis, Docker, and MQs like Kafka. Other courses help you understand, but you still have to study the technologies you'll actually use at work. In that regard, this course is very helpful for practical work. Conclusion: If you're someone who's somewhat familiar with scripting languages, you can save time by taking this course. It's very helpful if you approach it thinking you're taking over a project by inheriting code implemented by a previous developer. However, if you're new to Nest.js and don't have knowledge of Docker or other surrounding technologies, you might struggle. In the case of Prisma as well, it may not work if you don't match the version.
