Thank you, Younghan, for recording and uploading such a great lecture. I'm a junior developer studying in various ways, but this is the first time someone has explained such detailed parts, so I'm a little embarrassed, but I'm grateful.. ㅎㅎ I've only finished one lecture so far, but I plan to gradually take the other lectures~~ It's the start of the new year, so I hope you have many blessings and take care of your health!!
