I was initially overwhelmed by Next.js because I thought its server-side and client-side structures were complex and intertwined. However, I really appreciated how the course provided a clear overview of the entire structure and flow right from the start. Each lesson is very well-guided, making it easy for beginners to understand. I wasn't completely unfamiliar with Next.js, but the explanations were so good that I finally understood why I was using certain features in specific ways, which I hadn't fully grasped before. The lectures were so great that I also signed up for the TypeScript and React courses. Thank you for the excellent lectures.
