I always trust and listen to Younghan's lectures..! Now, even if Younghan calls a deer a rabbit, I really believe it's a rabbit. I'm a 3rd year web developer. From my perspective, it was easy to listen to with a light heart. I listened to it after work and while eating, and before I knew it, it was complete. I like that it neatly organized the content that I vaguely knew or the content that I vaguely knew. Now that I have some general knowledge, I listened to it lightly, but I think it would have been very helpful if I had listened to it when I didn't know anything at first. lol I recommend it to those who lack basic knowledge about HTTP or the web. If I get confused about something later, I think I'll just look for that part and listen to it again. Thank you for always giving great lectures.
