I didn't try the map API because it seemed difficult, but I had fun taking the class.

It's very helpful for beginners. I learned a little bit about how to use the API.

There is very little explanation of the code and its background technology. It feels like you just type it out and leave it at that. I expected it, but it was disappointing.

I wanted to learn about TypeScript grammar and use it with React, and I happened to hear a hot new lecture that had just been updated. I had used several APIs in the past, but I had almost just copied and pasted them. However, through this lecture, I learned how to use the official API documentation, and I gained confidence that I would be able to find and use the functions I need in the future. Also, TypeScript is not difficult, and the explanation is good, so I think even beginners will be able to follow along easily. Thank you for the great lecture :)
