After finishing the lecture, I found several points that would be helpful to apply to my work. The use cases were also explained well and helped me understand the content. However, I felt it was a bit a pity that there weren't more use cases. If it's difficult to include a wide variety in the lecture itself, it would be great if they could be provided as a document. Overall, the difficulty level is easy to understand, but it seems necessary for learners to review constantly and practice in various ways.
