I tend to be careful about buying lectures because I think I won't listen to them, but I bought them because I trust the instructor and I'm watching them. The official React documentation videos were really good, but this lecture is also really good. I've been really interested in UI lately, so I'm watching and learning a lot. In particular, I'm using TypeScript together, and I'm watching it as a way to review by rewriting the logic I wrote in Vanilla. In the process, I can hear the code implementation method that the instructor uses, so it's even better... I want to buy Part 2 when it comes out... It's good. The difficulty level is not easy, but that's why it's better. In particular, I like it even more because I can hear questions and answers from other students. I was surprised that the content I was curious about came up. Haha! Thank you for the great lecture!
