Hello Lunch-nim! This is Mike from Our Neighborhood Coding Studio. Thank you so much for leaving such a valuable review. It gives me great strength to know that you've followed through from the React course all the way to the Next.js Master Class. In particular, hearing you say it felt like "things I knew but were vague are now being organized" is the most rewarding feedback for me. I am truly happy that the 'fundamental understanding' I aimed to convey through the lectures reached you well. I will do my best to prepare the JS course you plan to take later so that you can complete those solid fundamentals. I would like to express my deep gratitude once again for consistently seeking out and supporting the lectures at Our Neighborhood Coding Studio. I want to offer a small token of appreciation. If there is an additional course you wish to study besides the ones you are currently taking, please feel free to send an email to jeony0535@naver.com at any time. I will send you a coupon you can use immediately upon checking your email. I will continue to repay your support with lectures that provide practical help for your growth. If you have any questions, please feel free to leave them anytime! Thank you so much :D
