I think the true value of Hodolman's lecture comes from review. (The regular lecture was also good!) In particular, when I was stuck while implementing a REST API on my own, when I wanted to write better code but didn't know the search keywords, when I couldn't get a clear answer even after Googling something, I watched the videos that were mainly necessary in these situations one more time, and it was very helpful every time. Thanks to you, I learned a lot about the parts to consider when designing a REST API, and I got a sense of how to study in the future. Thank you.
