I took the lectures in the order of JavaScript Web Games -> React -> Nodebird, and while working on a personal project, I got a job with much better conditions than I expected. I didn't get a job just by taking this lecture! But it was really helpful, and it helped me a lot when answering questions during interviews. I think it will be helpful for those who are preparing for employment as a front-end developer or who don't know much about the client and server data flow. Thank you~
