Thank you for the great lecture. It was so good, but personally, I thought I should have started from the intermediate level.ㅜㅜ There was a lot of content that overlapped with the Doit book, and it was good to review, but I felt a little frustrated when I had to use it in a hurry for practical work.. I had previously learned webpack, es6, and react..I listened to it in case I missed something, but I didn't have much personal time..ㅜㅜ It was a shame..ㅎㅅㅎ However, since the teacher explained everything in detail, I'm looking forward to the next lectures! I'm going to listen to them all. Thank you for the explanations that are easy to understand.
