Hello~ I am a job seeker preparing for the front-end, Younghan. I have been thinking a lot about whether there is anyone who can concisely lecture on only the content necessary for practical work among the scattered http-related knowledge, and I came across this lecture late and listened to it! I am really grateful that you clearly explain the role of each method and why each method should be used in relation to the http methods used when implementing the API, so that I can distinguish and use them better than before when implementing the function. For those who have not experienced the field, it is the most difficult and worrying about where to start and where to end their studies because the knowledge in this field is so vast. The same goes for the HTTP part. Thank you for creating such a high-quality lecture that can organize the content that is really necessary for practical work at once!
