Thank you for the great lecture. However, I am leaving this comment because there are some regrettable aspects from the perspective of a student. I think live coding is important from the perspective of a learner. The instructor sometimes stops and codes first, and then explains the changed coding in the video, but it is a bit difficult for the student to follow. The final result is provided as a file, so I am following the class while referring to it, but it is literally the 'final result'. In each lecture, the code is added and changed, so it is really difficult to follow the process that the instructor shows in the middle based on the final result. I think it is a really good experience to learn this lecture, but it is a lecture that makes me think it is really difficult to finish it when I see the instructor rushing(?) at every moment.
