I listened to it as if it was a final summary after studying HTML/CSS/Javascript once, and it's so great that the content that was a bit disorganized has been organized! I think the materials you shared will be really helpful after I get a job! I listened to part 2 first, but I think it would be good to study the backend as well, so I'm going to listen to part 1 and then part 3. Thank you for the great lecture!
