Hello, asam0707! This is instructor nhcodingstudio. First of all, thank you so much for taking the <React Master Class: Part 3 - Mastering Core Practical Libraries (TypeScript, Zustand, React Hook Form, TanStack Query)> course and for taking the time to leave such a warm review. I am truly glad to hear that the practice code provided was helpful for your learning! Since tools like Zustand and TanStack Query covered in this part are core elements of modern React practice, the process of learning by directly working with the code is very important. Taking your feedback to heart, I will do my best to provide even more detailed and in-depth explanations alongside the practice code in the future. I will continue to strive forward so that you can further sharpen your practical skills. To show my appreciation for your support, I would like to offer a small benefit. If there are any additional courses in our curriculum that you wish to take, please feel free to contact me at the email address below. I will send you a discount coupon immediately after checking.
