It seems like this is my first time writing a course review. I will try to explain the pros and cons. If I had to pick a disadvantage, it would be that the course was opened in 2018, so the version is very different now, about 4 years later. There were many inconveniences in that area. Since there were many students, the instructor's answers felt slower than in other courses, and there were many cases where students solved the problem themselves and posted a reply. It is good to look for solutions to problems, but there were some cases where it took more time than necessary. If I had to pick a advantage, it would be that the course opened in 2018 is still a course that many people are looking for. There are many students who are having the same problem on the Q&A board. We solve the problem together and think about the code again and look around. When I first listened to it, I didn't think the lecture was that clear.. When I listened to it the second time, I thought that I just didn't understand Vue well. If you listen, do a lot of code reviews and listen to the lecture repeatedly, I feel that the flow of the code and the concepts are well organized. Thank you for opening a good lecture. I listened well and will continue to listen well in the future.
