I really liked the course. From time to time, the author makes mistakes and debugs it on fly. Some of the code logic could be improved. I would go the other way from user experience and code scalability.
But still it's a really robust course. And I really recommend it to everyone trying to step up their skills from React to the modern Next.js 13.
He could cover more about the differences between the current version and the previous version.
Indeed, there is not much Typescript explanation. But Prisma ORM introduction is quite nice.
All in all, the author shows how to build a real project with user authentication, registration, password encryption, storing data in a database etc.
