It's not my first time coding, but before, I just hurriedly solved the problem in front of me, so I just took the code implemented by others without understanding it and used it to fit my code environment. So, I happened to see Alan's lecture introduction with the intention of starting over from the basics, and I had a strong feeling that this guy was the real deal, so I inquired about it early in the morning and signed up for the lecture. ㅎㅎ.. The lecture is designed to be watched three times in total, with a preview (infraun) + review of the preview (study) + real-time lecture (every week), although there may be slight differences for each person. For parts that I really didn't understand, I looked at it several times as a reference for the frequently asked questions or other people who had already asked, and the study environment in the lecture was so well-established that I didn't feel the need to search for it on the portal site. After listening to this lecture, I can't write the code right away, but unlike before, I can understand it and create my own code. The code is clearly visible at a high level of understanding. I'm still in the beginner stage, but after taking the lecture, I have a clearer idea of the future direction. Thank you for your sincere efforts in everything ~
