At first, I got off once because it was deeper than I thought and felt like a college theory lecture. There were many terms and concepts that I didn't know, so I was frustrated. (They wrote that it wasn't a beginner course in the learning target, but I thought I wasn't a beginner, but I was.) However, I didn't think it was right to give up the lecture because I didn't know many things and was frustrated, so I searched for concepts that I didn't know and listened to them. So, even though there was no chapter that took more than an hour, I listened to it while understanding it every time, following the example codes, and checking them in the console. I think it took more than an hour. In the end, I finished the course this week. Honestly, I can't say that I understood everything yet, and there are still parts that I don't understand, but I feel rewarded for consistently completing one lecture. I was able to understand basic concepts of JS, such as the var let const keyword, China arrow function, and after skimming through it once, I was able to understand many things, which was good. I will continue to listen to the advanced lecture and DOM lecture. Thank you.
