Hello, Pineapple! 😊 First of all, thank you so much for completing 33% of the [DOM Complete Mastery Part 1] course and leaving such a valuable review. I'm truly delighted that you're steadily learning DOM structure navigation and manipulation through this course, which is fundamental to web development yet can be challenging when you dive deep into it. I hope this has been a time for you to build a solid foundation, starting from understanding how HTML is converted into objects, rather than just memorizing functions. This structural understanding you've built in Part 1 will be the key foundation for the interactions and browser optimization that will follow. You've passed the one-third mark, and if you keep this momentum and complete the course, you'll definitely view code from a completely different perspective than before. If you have any thoughts or additional questions while learning, please feel free to share them anytime. Your valuable feedback is a great help in making future courses even better. I will also do my best to always be helpful to you and support you along the way. Part 2 (Events and SPA) and Part 3 (Rendering Performance Optimization) courses are also ready, so I highly recommend you take on the challenge to complete them all. If you encounter any difficulties during your learning, please feel free to leave questions on the Q&A board or through the open chat room: https://open.kakao.com/o/gC10Fnoh. Thank you once again, and I sincerely support your enjoyable development journey. Have a great day! 🌿
