While taking this course, I felt several disappointing aspects. First is the course management and update section. The course hasn't been fully updated yet, but there's no guidance whatsoever about the update schedule or content. The last lecture in Section 3 and Section 4 only have a "Coming Soon" message, and it's frustrating not knowing when or what content will actually be added. Additionally, I left related questions on the course Q&A board, but after nearly a month without any response, I got the feeling that the course is being neglected and not properly managed. Second is the lack of conceptual explanations. For example, in the video about creating a Zustand store in Section 1, without explaining "what the concept of a store is and why it's needed," it immediately shows creating a store folder and the code for generating a store. As a result, core understanding like "what problems Zustand solves as a library and how it differs from Redux or Context API" is missing, making it feel like a course where you just mindlessly follow along. Third is the limitations of the practice approach. Rather than directly coding and implementing small projects step by step, the structure was just showing PDF materials and guiding usage methods only. While this approach is convenient for quickly skimming through basic usage, I felt the learning effectiveness was very poor since there's no process of actually writing code and internalizing concepts. For example, there were no opportunities to experience how state management is reflected on the screen, what errors occur when you make mistakes, or how to solve problems that can arise when implementing asynchronous processing, so it remained at the level of simply learning usage methods and felt difficult to lead to substantial growth. In conclusion, I felt that course management was also inadequate, and the content itself didn't feel in-depth, so I didn't receive much help from it.
