Hello, Alain Delon! This is nhcodingstudio, the knowledge sharer. First of all, I would like to sincerely thank you for taking our course and for leaving such honest and valuable feedback regarding the level of the lectures. As you mentioned, since this course focuses on solving deep, practical concerns encountered in the field, it can be the "most reliable weapon" for those with foundational knowledge, but it may feel somewhat difficult for beginners. I am deeply grateful that you are sticking with the learning process despite the challenging content. Using your feedback as a foundation, I will do my best to convey even high-difficulty concepts more clearly and deeply in the future. To reward the passion you have shown while studying, I would like to offer you a small benefit. If there are any additional courses you wish to take among our curriculum, such as the Next.js Part 3 or the React series you mentioned, please feel free to contact us at the email address below. I will send you a discount coupon immediately after checking. * Inquiry Email: jeony0535@naver.com I will continue to cheer you on so that you can further sharpen your practical skills through this course. Thank you once again for your precious words! :D
