It was honestly difficult to call it an introductory course. I felt like it was more like a quick glance than an introductory course. You might think that an introductory course and a quick glance are similar, but there is almost no explanation of concepts and it is just reading code, so it is difficult for beginners to follow. For parts that require explanation of concepts, they tell me to listen to them in other lectures, so I didn't gain much knowledge compared to what I expected.ㅠㅠ However, since this lecture is originally about looking at example code and skimming, I will go to other lectures to find meaning in what I skimmed. Thank you for uploading the course for free, and thank you for your hard work!
