I listened to the lecture well. Good points: The lectures were short and easy to understand. However, each one was explained thoroughly, making it easy to understand. I understood the comparison between Vue2 and Vue3 well. Request: The open source version will continue to be upgraded in the future, and new things will come out. I would appreciate it if you could give lectures on the core parts at a low price, even if it is short, like this lecture. I don't want to study alone. I look forward to the next composition lecture. Thank you.
