Wow... Such a high-quality lecture... is being released for free... Thank you so much! It's a great help to those who are new to node.js! You can think of it as a paid lecture. The debugging time due to the instructor's mistakes in between was also really good! Being able to see the debugging directly is something you can't learn even if you pay money... If there are people who say that the quality of the lecture is low because it takes time to debug, I think they are delaying their own potential development. Learning about the process of solving mistakes is hard to learn even in the field. It's a problem-solving process, and I really liked it! Are there any future lectures? Even if it's a paid lecture, I'm willing to take it! I'm really learning a lot!
