I listened to everything from the first React I encountered to the first Redux I encountered. In fact, after learning React, I looked up blogs and saw that there are many simple state management libraries these days, so I almost didn't listen to Redux, but thanks to the phrase in the lecture introduction [It is important to build the basics of state management through Redux!], I ended up learning Redux. Thinking back now, it was really fortunate. While working through Section 1 to the last mini-project, you can learn about Redux from its very beginning(?) to Dux, thunk, slice, saga, etc. to make up for its shortcomings. If I had learned from the simpler part, it would have just been spoon-fed learning, but since you can learn how to develop it step by step, I think it is a good lecture to become familiar with Redux in a short period of time. However, since the difficulty level is set to "beginner," it might be a little overwhelming if you think of it as an introductory level. It is my first time with React, but I have experience with backend, so I was able to learn it intuitively(?). Even if I didn't understand it, I listened to it comfortably as if I was listening to a column, and instead, I made sure to do the project myself. And then I learned by checking the documentation again. However, even if I didn't understand it at first, I just listened to it thinking, "Oh, okay~", and the next section supplemented that part, so it's good to have time to understand it naturally once more. React seems to be a library that's developing very quickly. I hope that Sopl will come out with many more lectures in the future!
