This is the best lecture for developers who are new to front-end. The teaching ability is so good, from the voice, curriculum, to the content of the lecture itself. What I felt was that the lecture was well designed is that, unlike other lectures I've taken, each video is specialized for a specific topic. So, even if you don't listen to it from the beginning and just watch the lecture video, you can understand the topic. One thing I regret is that it would have been better if the lecture was divided into React beginners and Next.js beginners. I think it would have been better if the target was divided into two and it went a little deeper. As someone who only developed with React and is now starting with Next.js, it was a selfish thought.
