As a lecture collector, I have taken many lectures, but this is the best lecture! First of all, the instructor is proficient in the latest TypeScript grammar and React grammar, so just by looking at it and thinking about when to use that, I feel like my skills are improving. Originally, I didn't understand it well just by looking at the book and the document, but I learned it again by thinking, "Oh, that's how to apply it like that." I think it would be better for juniors with 1-3 years of experience rather than beginners. First of all, the lecture itself can be applied directly to practice, and it even covers the advanced parts of React. I definitely recommend it to those who want to grow from juniors to mid-level developers by thinking about how to make better codes, not just simple implementations. Now, I feel confident that I can implement any UI I encounter. ㅋㅋㅋㅋ Even if I don't understand it 100%, I think it's great that I can apply it to practice by looking at the code organized by chapter again. Just by taking this lecture and having the completed UI code, I think it's worth the lecture. I hope the next part comes out soon!
