I am a graduate who completed the offline CodeCamp Full Stack course! I heard through text that Mentor Wondu's lecture was uploaded to Inflearn, so I came running. As a developer, I would like to talk about this curriculum from the perspective of a developer. If you want to become a junior who considers the performance of a project, it seems to be the perfect curriculum! In addition to memoization used in React, which juniors can often encounter, I also learned repaint and reflow based on browser rendering principles, so the range of things I can consider when refactoring has definitely expanded! And you taught me patterns that can help me write code in a way that is a little more advantageous for maintenance, and you gave me tips, so I am personally using them well! I can't believe I'm seeing this lecture againㅠ I don't know if Mentor Wondu remembers me, but I miss youㅜㅜㅜ No Wondu! No Gain! Forever!
