The structure and principles were explained first, followed by hands-on practice and explanations using actual code, which made the flow well-organized and easy to understand. The practice sessions used clean, concise code examples, making it easy to follow along without any burden. It was also convenient because the instructor showed how to set up the practice environment simply. The highlights, such as boxes and lines in the lecture videos, were intuitive, and Yalco's voice was great for staying focused. I was able to establish the concepts in a short amount of time, and I think it will be very helpful in practice. I highly recommend this to anyone who needs a React course.
