"Hello wkdska1590 😊 Thank you so much for leaving such a valuable review! 🙏 It must not have been easy to implement a complex service like Notion using only vanilla JavaScript, but I'm truly happy that you stayed with us until the end. I hope this course helped you not just with implementing simple features, but also with designing the overall service structure and understanding the flow of data handling. If you have any parts you'd like to explore more deeply or any questions that come up during your learning, please feel free to reach out anytime. 💬 Based on your valuable feedback, I'll work harder to include deeper insights into 'why such structures are necessary' in future content. I hope you have a wonderful day of coding today, and I'd love to see you anytime in our open chat room! 🌿 👉 https://open.kakao.com/o/gC10Fnoh"
