In addition to the front-end knowledge, I liked the advice you gave me on how back-end developers should develop screens. In particular, I really agreed with the idea that back-end developers who have experience creating screens can design better API specifications. I was able to follow along and learn without any problems thanks to the meticulous consideration you gave, such as using IntelliJ instead of VSCode for the practical training. I have received help from Foo in many ways before, and I am grateful that you prepared a lecture with good content this time as well. I will eat well with gratitude :D
