First of all, since my skills are far inferior to the instructor, I quickly skimmed through the entire lecture rather than reading it thoroughly. This may be unpleasant for the instructor, but I will explain it from the perspective of someone who doesn't know. 1. There is a problem with the lecture sound. 2. The video quality is not that bad, but I am not completely unfamiliar with React, but I do not have a reference project, and as someone who is seeing React Native for the first time, it is not easy to follow. The lecture skips over parts here and there. Of course, it may be because I do not understand it, but there are definitely parts that are not recorded between the first and second lectures. And there are too many OBS tool changes during the lecture. 3. It felt like a lecture that was given alone. I do not know if it is because of the time constraints, but it feels like it is skipping ahead rather than helping the audience understand, so it is a bit disappointing. In conclusion~ I learned that React Native looks like this. And I also learned that mobile apps use these things. Later, ah~ I saw something like this in that lecture, and I think it will be helpful when I do it. Thank you.
