It's a good lecture except that I have to press the next lecture button too often. The lecture structure is not SI-style project source implementation, but rather, there is a lecture flow that says, "I'm going to do this and that, but I have this and that problem, and I have to use this and that function, and if a problem occurs, I can do this and that." But because the session is cut off too often, I end up missing the big picture. Other than that, everything is good. If you read Jang Gi-hyo's book and Vue.js Quick Start together, it will be helpful in many ways.
