It was a short but very informative lecture that explained the simple but essential content in detail! Thank you.

As soon as the lecture starts, the test code is explained with the code created without the code implementation process, so I don't think there is any reason to pay for a lecture that is not friendly to the students. As of October 12th. --- The reason I thought the lecture was unfriendly was because I thought there was no sample code provided to follow the lecture, so I felt uncomfortable writing the same test code while watching the lecture. However, I found out later that the sample code was provided through a Github repo link. I misunderstood and left a wrong review. I'm sorry.ㅠ The lecture itself is sufficiently explained. It's concise and good. I left a comment because I was upset, but thank you for your kind reply. I don't know if you explained it before, but for those who missed it like me, if you attached it in the lecture materials section like this: Sample code provided -> [GitHub link], it would be helpful. I would appreciate it if you considered it!
