This is the first lecture I wrote after I decided to start studying development as a non-major. Since I have nothing, I thought I should at least get insurance, so I registered for the course and started studying, and I have been watching it from time to time. I can't say that this lecture alone will change anything drastically, but it is a lecture that definitely gives me a stepping stone when I start, and thanks to it, I am gradually learning how many developers have grown. If you don't use it, you can just think of it as a lecture that is just okay, but for those who really want to settle down, I think there is no better guide than this. I don't know if all of Inflearn's lectures are unlimited in duration, but I personally highly recommend it to those who are just starting to study, and I recommend that you start studying quickly by taking the part you are interested in before you start studying, and I also really recommend it to those who are wondering if I am on the right path while studying. If you look at Han Jeong-su's lecture + link, why he left this link, and what path the subject of the article or video in the link has taken, I think it will be more helpful than simply studying development a little more during the same amount of time. Personally, I recommend that you first watch the parts of Mr. Han Jeong-soo's video that interest you, and then definitely watch the videos and Tistory articles about Lee Dong-wook that Mr. Han Jeong-soo recommends.
