Two things were great. - Even beginners who learned Fortran in college and are watching intro Python/pandas online lectures are given the courage to grasp concepts and try. While listening to the lecture, I tried 2 apps and it seemed possible. Although there are errors I'm fixing, I think I can quickly make it once I get the hang of the features. 바이브 코딩 was amazing; I could implement features I only imagined into an app to some extent just by chatting a few times. (Of course, it seemed like a lot of knowledge was needed to implement commercial-level features.) - Using the bolt tool makes it differentiated. (Though I don't know what the difference is from the cursor...). In conclusion, I thought it was a good lecture. For the firebase or API setup parts, it would be more convenient if there was a textbook.
