It's good because I can organize a lot of content quickly. I studied FastAPI on various platforms and read books, but this was the easiest to understand and learn properly. I was a little worried because there was a lot of live coding. I thought, 'Wouldn't it be boring?', but it was easier to understand because the prepared logic was quickly recoded and explained. In the previous review, you said that the microphone was a bit problematic, but it was improved and not very inconvenient. It's a little disappointing that ORM is missing. I really want to hear what you think about ORM and how to use it well. I really hope the next backend in-depth lecture comes out!
