As a current developer, I wanted to learn another language, so I bought and studied the book "Do it! Introduction to Vue.js" about two years ago. At the time, I didn't have a chance to use it in the field, so I gradually forgot about it. Then, I suddenly decided to study Vue.js again before the end of the year, and while looking for a lecture, I found this lecture. I found out for the first time that the author is the same as the author of the book that I studied on my own. So I thought it would be helpful to take more lectures, and I think I chose it because the roadmap was good. As a beginner in Vue.js, I think it was very helpful to study the book and lectures in parallel.
