This is a lecture by Zerocho that I trust and watch! I tried to study Next and looked at the official documentation, but I couldn't read it well, so I think it's faster to watch all the lectures and then look at the official documentation. Usually, I watch all the lectures and then study the core functions, and then I remember only the keywords of the functions in the official documentation. If I need a function while working, I look it up in the official documentation and apply it. The lecture time is not long and it's well-divided, so it's good to watch it on the subway or when I have free time, and it's also very convenient to look it up again when I don't understand something. I used to use React-query only as a function that I used to use, but I think I've been using it better after listening to the explanation this time!! I also used Zustand for the first time this time and learned about MSW and various libraries as a bonus. I'm so grateful that you've consistently uploaded good quality supplementary contents such as distribution and web socket that are good to know in the field. Please keep up the good work and continue to be active! ㅎㅎ
