I am currently a student who has completed about 20% of the course! When I did a web project with React in the past, I studied on my own as if I was heading to the bare ground. It was too difficult, and there were many things I didn't understand. Then, when I joined a company, I was going to be in charge of the web, so I studied again and came across the lecture. The lecturer's ability is so great that I even said, "This is a free lecture..?" I don't know why I only saw it now, it's such a good lecture!
