I am a person who is taking the lecture again after the renewal. In my opinion, the previous version was also very helpful, but after the renewal, the screen quality, code readability, sound quality, etc. were all more stable, so it was easier to watch. I remember that the original lecture was about 20 lectures, but you added many basic explanations so that beginners can participate from the beginning, and you added lecture time and number of lectures so that we can complete the examples together, and above all, you explained the principles one by one so that I could understand them. I can say that it is definitely better than the previous lecture. Personally, I am very satisfied. Thank you for taking the time to renew it, and thank you for your hard work.
