- The advantage of this lecture is that it is well-organized and rich in content. However, if you have already experienced a project using vuejs, you don't need to take the course.. You can easily skip the component writing part in the beginning, and you can think of it as gaining the instructor's know-how. I was wondering how to test vue.js, and it was good because the explanation for that part was well done. The lecture was too short, so it was a little difficult to get through. I'm looking forward to the typescript lecture.
