Hello, Instructor Jeonghwan! I am a student who first entered the world of development through your book, "React in Bite-Sized Pieces." At the time, thanks to your book, I discovered the joy of development and received so much help. There was a period when I faced setbacks during my job search and almost gave up on my dreams, but when I looked back at my happiest memories, it was always the version of myself that was coding. When I gathered the courage to return, I saw how much you had grown into such an excellent instructor, and I chose this course without a second thought. Thanks to the perfect quality and explanations that met all my expectations, I learned so much that my hiatus felt insignificant. Thank you sincerely for lighting my path once again. I will always be rooting for you! Thank you.
