I enjoyed listening to it and it was helpful.

It was good as an introductory lecture. I think I will take the actual lecture when it comes out. Thank you for making a good lecture. [2 things I regret] - I wish the next lecture had a clearer image quality - If you upload the example code to GitHub, I can save typing time, so it will be helpful for studying.

Since I know a little about functional programming, I was able to finish the course in two days by spending evenings. I have no practical experience with RxJS, but I was interested in new technologies. In future lectures, I hope that UI or practical web apps using RxJS are added. Or, React + RxJS applications, etc. The lecturer briefly mentioned the next lecture during the lecture, but I wish that part was added to the lecture introduction. Lastly, the overall lecture quality is good, but the total lecture time seems a bit short.
