I'm a publisher who is diligently studying React because I want to switch to being a front-end developer someday, or at least do some publishing in a React development environment :) Most React lectures teach similar toy projects, which was a bit tedious, but this one is so much fun, maybe because it's about creating UI! I've made all of these UIs at least once with jQuery or JavaScript, so it feels a bit more familiar... I think about how I would have made it first, and then listening to the lecture makes the instructor's perspective so interesting. And, I feel like I've become a bit more familiar with Observer. I've used it a few times in the field, but I didn't feel like I had completely gotten rid of it, but after using it a few times while listening to the lecture, I was like, 'Ah~!' Of course, my basics are still lacking, and it takes a while to rewatch and think about parts I don't understand because the instructor's mind works so fast, but even so, it's a lecture that I get a lot out of! If there is a publisher around me who is studying React, I would definitely recommend this lecture 😊😊 I'm planning to purchase Part 2 soon! Thank you for always giving such great lectures :)
