Wow... I bought it even though it was a little expensive... I'm so embarrassed that I tried to take the coding test with this skillㅠㅠ I listened to it halfway through and I'm so satisfied... I thought I was somewhat confident in implementing it and took this lecture for the last time, but when I encountered a problem, I felt more at a loss than I thought... That's why I struggled a lot in the beginning lecturesㅠ As I gradually progressed, I started to see the order of how to implement it and my speed started to pick up. I think I'm definitely writing more subjective code than before! It's expensive, but I think it's worth the money!! Those preparing to be a front-end developer won't regret it!
