Thank you, Hewbie! Your valuable feedback really gives me great strength. It's because of feedback like this that I can prepare lectures with more passion and create better content. I will continue to prepare even more and richer good content to meet you in the future. If you haven't taken the [DOM Complete Mastery Part 2] – From Events to SPA, Essential Engine for Interactive Web course yet, I recommend taking it without burden as it naturally extends what you learned in Part 1. And currently, [DOM Complete Mastery Part 3] – Critical Rendering Path Complete Analysis and Practical Optimization course is scheduled to be released at the end of August, so you'll be able to perfectly master browser rendering performance and optimization. 😊 And whenever you have questions or need help with development, please feel free to use the open chat room below. You can communicate with other students, and I also visit frequently to share concerns together! 📮 Open Chat Room: [https://open.kakao.com/o/gC10Fnoh] I sincerely support your development journey always. I hope we can meet again in the next course! 🚀
