One-line review: I paid without much expectation, but I felt that this lecture was good Reason for payment: I paid for another lecture, but I didn't have time because of work. The new one is conducted in a modern browser environment, so when the time came, I watched the existing paid lecture, but it was too long and boring, so I looked for a short one and paid after looking at the table of contents Good points 1. I studied deeply by opening the browser and debugging, and it taught me the principles (I was able to study deeply, not just implement simple things) 2. It focuses on next.js without unnecessary explanations (scss, css.module, react, cache background knowledge, etc.) 3. The teaching method was good While checking out the branch, it only removes comments, shows various comparisons, and shows the differences and how to use them efficiently (It explained the differences and how to use them without unnecessary details) 4. The price is a good deal I think this price is a great deal for this level of quality. 5. The answers to questions are very detailed They took this much time to answer? It felt like that 6. Tailwind is not used X It was so inconvenient to memorize styles for styling and style HTML tags, but fortunately. 7. The official documentation was also reviewed, so the cost of having to look at it myself was reduced 8. I was frustrated because I didn't know much about SEO, but I was able to learn it more easily than I thought, and the summary was very good 9. I learned why I should write HTML code that considers web accessibility Personally, what I would like to see added 1. When using next.js with monorepo in vscode, it would be great if you could also tell me about debugging settings, because it's not easy. (By debugging settings, I mean breakpoints. Monorepo debugging settings are not listed in the official next.js documentation.)
