After attending the national academy for 6 months, I was wondering what kind of developer I should become in the future. Then, after watching Youngbo's Inflearn interview video, the word "user-centered" really appealed to me. So, I finished Youngbo's beginner course today. If the academy teaches you because you have to use it in practice, this lecture was a lecture that scratched my itchy parts by explaining how the JavaScript engine works and why and where this function or method is used. There were many other great parts. I will listen to the remaining three lectures and continue to study repeatedly. Thank you so much for the great lecture! It's a fun lecture that I don't regret spending money on! Even though I'm a prospective developer, I will always try to think of the user as the center.
