I watched lectures 1, 2, 3 and vue3 1, 2. It helped me a lot in understanding the overall content. However, since I haven't used the router, store, and composition APIs that I use in practice yet, I think I should take lectures 4 and 5. I've been listening to and studying the 23-year Vue lectures so much. I want to become a proper Front End developer in 24. ^^ Thank you for the great lecture.
