Hello, I enjoyed the lecture very much. Even though I took the course after reading the Next.js official documentation first, the early part of the lecture where each topic was clearly addressed with the flow of problem → background → solution helped me organize my understanding well. I was particularly impressed by the explanation approach that unfolded from the perspective that development is ultimately about problem-solving, and the parts where you explained based on actual code along with background knowledge were very helpful. I think this lecture can serve as a good guide for those who are just about to introduce Next.js or those who are considering introducing SSR after feeling the limitations of CSR. However, there were a few disappointing aspects. In the early routing implementation part, when you started explaining with code written by generative AI, it was confusing from my perspective of expecting actual internal implementation code, and I had doubts about the direction of the lecture. (Of course, my misunderstanding was cleared up when you later explained based on actual code.) Also, curriculum title compositions like path automation or template.tsx animation that you implemented directly might feel like official Next.js features, which could cause some confusion, so it would be better if you separated them into separate sessions or clarified the explanations. And personally, I was disappointed by the lack of explanation about cache strategies that have become important with App Router. There were also some parts in the lecture flow where mentioning later content early on made it feel like prerequisite knowledge was needed. Nevertheless, overall it was a well-organized lecture that is helpful for practical work. Thank you.
