I am a student who has taken the course from Introduction to Web Development to Mastering React! One-line summary: If other lectures are just coffee, this lecture is T.O.P. 😎 The instructor explains complex concepts easily, and solves the shortcoming of self-study lectures, 'difficulty concentrating on your own' by guiding you to practice directly in between. Every time I hear the words "Stop for a moment and try it first" in the middle of the lecture, the tension that had been loosened returns, and it was a great help in solving problems proactively. In addition, the lecture notes and the code in the GitHub repository are well organized, so it was very easy to follow when errors occurred during practice or when reviewing later. (It must have been hard to organize everything like this, but thanks to you, I was able to focus on the content. 😁) In particular, I was impressed by the fact that you provided various insights so that I could continue to study on my own, not just the lecture content, and that you tried to teach me as much as possible when I saw the additional and reference videos. 🤗🤗
