This lecture is really like a shower in a drought. Looking back on the past year of analysis design at SI company, the messy design that bypassed controller and service, SQL-oriented coding, and ctrl Cv, everything was a mess and I was depressed because I didn't learn anything properly. I was going to do a side project to change my mood, but I thought I should organize the basics again, so I clicked on Inflearn's Kim Young-han's lecture curriculum, and the HTTP lecture that I hadn't organized was the most appealing, so I paid first and finished it yesterday and today. Thanks to the lecture with a beginning, development, turn, and conclusion, I easily established the concept of HTTP and I feel good because I gained confidence that I can design and develop better APIs in the future. I will try to become a better person than yesterday by watching the lecture a few more times and learning the remaining lectures. Thank you for uploading a good lecture.
