Hello, Hullalla! 😊 Thank you so much for leaving such a valuable review! 🙏 I trust that through this Part 1 course, you've gradually mastered DOM structure navigation and manipulation, which are fundamental yet challenging aspects of web development when you dive deep into them. I hope this was a time where you built a solid foundation, not just memorizing functions, but understanding the process of how HTML is converted into objects. This structural understanding you've built in Part 1 will be the essential foundation for the interactions and browser optimizations that will follow. If you have any thoughts from your learning experience or any additional questions, please feel free to share them anytime. 💬 Your valuable feedback is a great source of strength in making the next courses even better. Part 2 (Events and SPA) and Part 3 (Rendering Performance Optimization) courses are currently available as well, so I highly recommend you continue this journey without missing the flow! If you encounter any difficulties during your learning, please don't hesitate to leave questions on the Q&A board or in the open chat room. Once again, thank you, and I sincerely support your enjoyable development journey, Hullalla. Have a great day! 🌿 👉 https://open.kakao.com/o/gC10Fnoh
