Good points 1. It is easy to understand because it shows a diagram that shows the structure of the app at a glance. 2. The depth of the explanation is consistent (mainly explaining the operation of the code briefly), so the lecture can be kept concise. 3. The instructor's manner is neither too light nor too stiff (not crazy or too fast). If you are interested in taking the class, - HTTP, ES6 knowledge - Basic tutorial and hook tutorial on the official React website - Node official website tutorial I think you will be able to follow along if you just look at this much. Thank you for sharing such a great lecture for free! Thanks to you, I learned React more easily.
