Hello Byeon Giwon 😊 Thank you so much for leaving such a warm review. 🙏 I'm truly delighted that you found the course engaging. This [DOM Complete Mastery Part 3] was designed to follow the entire process of how browsers render screens from start to finish, allowing you to directly experience moments when performance actually improves. If that process came across as interesting to you, I feel incredibly rewarded as the creator. Every single word of encouragement you've left becomes a great source of strength that keeps me going with these courses. I'll continue to bring you performance optimization courses that can be directly applied in real work, as well as deeper content like the upcoming React rendering series. If you have any questions during your studies or topics you'd like to learn more about, please feel free to share them anytime. 💬 I'd love to create an even better learning journey together through our conversations. Thank you once again, and have a wonderful day! 🌿 I'm also running an open chat room where students can discuss together, so please feel free to drop by when you have time. 👉 https://open.kakao.com/o/gC10Fnoh
