I feel like I gained a lot through this lecture. - For someone like me who was stuck on tailwindcss v3, I learned what changed in v4. - How to more efficiently use zustand and @tanstack/react-query, which I already had experience with. - shadcn/ui, which I was interested in but felt a bit overwhelmed to start using. - The directory structure of files within a project. - Although it was just a taste, how to use supabase (sign-up, etc.), which I was curious about as someone who only knew front-end. Since there was a time gap between when the lecture was first filmed and when I took it, there were some differences when installing or applying libraries. I followed along by looking things up myself, which made it fun and helped me complete the course. Thank you for the great lecture! 😊 Based on what I've learned, I will try to incorporate these skills into my own projects by starting a side project or refining previous ones.
