I enjoyed the lecture. At first, writing implementation examples of React hooks seemed helpful, but as it went on, it felt a bit dragged out. In Part 1 of the React course, there were many hands-on exercises which made it fun, but this course didn't seem to have as many, and since the lessons were long, it felt a bit loose toward the end. Still, I really enjoyed listening to it, and thank you so much for always answering my questions. For those worried because it's been a while since the course was released, there don't seem to be any major breaking changes up to version 19, so I think it's perfectly fine to take it. Thank you for the great lecture.

Everything is great, but you have way too many typos and missing pieces of code.

I have gained a clear understanding of the role Webpack plays and have come to understand the various options it provides. Additionally, I was able to learn how to properly optimize JS bundles for both development and production environments..!!

Thank you for the great lecture!

In the rapidly evolving web landscape, I believe fundamentals are always crucial. With a strong foundation, you can adapt to future changes. Kim Jeong-hwan's lectures always teach those fundamentals.

I finally completed Part 1! Since this is my first time encountering React, it wasn't easy to understand everything at once. However, thanks to the step-by-step curriculum that progresses gradually, I was able to follow along well. And while the teacher was worried that students might find the orthodox teaching style boring... I was actually sadder when I couldn't understand things😭😊😊😊 The journey from pure JavaScript to React was like a ray of light for me, as I've been feeling anxious lately. Even though I'm entering my third year of development, I've always felt uneasy deep down, thinking that I'm just getting by in the field relying solely on the power of frameworks and tools without a solid foundation. I felt like I was constantly missing something, but it seemed too late to revisit the basics now, and I wondered if it might be inefficient in a world where AI does everything. However, after studying Part 1 with the teacher, although the struggle of not understanding everything remains, my mind has become much more at ease. Above all, my motivation to study has reignited!! I won't just rest on the joy of completing Part 1, but will work hard on Part 2, dreaming of the day when I can think and develop like the teacher!

This is innovation.

Thank you for sharing the internal workings of React APIs, which has helped me feel like my understanding of the framework has improved. Thank you.

I'm watching the core web development lectures and also checking out the free lectures - watching it for the second time and now the content is starting to make sense. Good good

I think this would be essential for those who aren't familiar with HTTP and browsers. Especially for those working with Javascript, I think it would be even better if you follow along with the typing. Since I don't have occasions to use Javascript, I only followed along with the protocol and caching parts and just watched the rest with my eyes, but it was very helpful.
