It's really hard to find a lecture this informative, but for the first time, I feel like I spent my money well on a paid lecture. CSS is inevitably boring, so whenever that happens, I listen to the JavaScript lecture in conjunction with it, and when I think, "I don't know this," the lecturer explains it like a ghost, so I can listen to the lecture without any difficulties. I only listened to Part 2, but I like the lecture style so much that I'm going to listen to Part 1 quickly while waiting for Parts 3 and 4. I looked at the Part 1 lecture content, and it's as informative as I thought (login and REST API). Thank you for always giving great lectures.
