I had a hard time figuring out how to start studying React for the first time, but I got a lot of help thanks to the concise lecture structure. Since each lecture and the entire lecture structure are not long, I think I can watch it over and over again, which is also an advantage :) On the other hand, since you also covered vanilla JavaScript, it was easy to understand what kind of problems React was a framework that appeared to solve. However, both are still difficult.. ㅎ_ㅎ From now on, I will watch it over and implement it several times to solidify the basics of front-end development. Thank you for the great lecture.
