I am leaving a review because I was very satisfied with the lecture! I am a front-end developer, but I have been stuck on the Page Router stack for a long time. I have tried App Router, but I kept using Page Router because of my familiarity with it... But I thought I would try to follow the latest trends by taking this lecture, and the quality was much higher than I expected. One of the reasons I kept going back to Page Router was that I didn't understand App Router properly. By taking this lecture, I was able to understand how App Router works, and I gained confidence in App Router while working on a small project. If I had any wishes for the next lecture, it would be nice to have a practical (or advanced) version that includes all the settings because sometimes when you set up App Router, the design system or other libraries don't work properly, making it difficult to set up! Thank you!
