This is a lecture that you can trust and listen to. It is a guaranteed hit. However, since I watched all the HTTP lectures, I think it was not included, but I thought it would have been good to include a lecture explaining Restful API. I think it was hateoas rest that explained from step 0 to step 3, but I can't remember it well now. I believe that all the contents of this lecture will be applied to the practice in the follow-up lectures. It is better than any other lecture. It is clearer than any explanation.
