Wow, the lecture is really... I'm halfway through it now! In my case, I'm a 4th year college student who is taking the course right away without listening to the intermediate and introductory courses! If I had listened to the intermediate course, I think I would have been able to understand it with a high level of understanding, but since the instructor explained it again, I was able to understand some parts without listening! However, it is certain that I would understand it better if I had listened to the intermediate course. Since it is a lecture that includes practical parts and the instructor's tips..., the instructor explained the concepts in detail, and I was surprised that he just told me right away when I was like, "Huh? Why is this like this?" It was so surprising that he could hear me. I really don't regret the money. After finishing this course and getting my part-time salary, I plan to listen to the instructor's webpack and PWA courses together!!! I will use the vue.js I learned from instructor Jang Ki-hyo in the upcoming hackathon and win!!! Thank you for the great lecture!
