I think it would be more helpful for those who have learned it once to follow the example rather than those who are completely new to it. Rather than explaining basic terms, it explains in a way that you can apply it right away under the assumption that you already know it. When you focus on coding, there are times when you don't talk for a while, but it would be better if you consciously continue talking. As I was coding along with the lecture, I thought I could input it right away if you talked, but I had to look at the screen. And when the teacher finished coding, if you paused for 1-2 seconds and then continued, it would have been easier to pause on that screen and compare it with my code, but since you went too far, I felt a little uncomfortable because I had to find the screen where the code was completed and pause it. I liked that you gave me a lot of great tips~ I recommend it to those who want to learn it once and then review it in a short lecture!
