Thank you, Byeongjoo Jeong! I sincerely appreciate you leaving such a valuable review and positive feedback! 🙏 I'm truly rewarded to know that you've gained a deep understanding of the core principles of structure navigation and manipulation through the DOM Complete Mastery Part 1 course. I hope this course has gone beyond simple knowledge transfer and will be of great help when you work with DOM in actual projects. Currently, Part 2 (Events and Dynamic UI) and Part 3 (Browser Rendering & Performance Optimization) are also available! 🚀 These courses cover expanded topics from event delegation and advanced event handling to browser internal rendering pipelines and performance optimization techniques, so I ask for your continued interest. I'm confident you'll gain insights that can be immediately applied in real-world work. Also, with gratitude and encouragement, please feel free to use the open chat room below whenever you have questions or need help during your development process. You can actively communicate with fellow learners, and I frequently visit to share concerns as well! 📮 Open Chat Room: [https://open.kakao.com/o/gC10Fnoh] I wholeheartedly support Byeongjoo Jeong's development journey and look forward to seeing you again in the next course! 🌟
