*The content is good. However, I think it is a pity to pay for it. It would be better if it was free or less than 3,000 won. I saw that the instructor has a follow-up lecture. I think it would be appropriate for people who are satisfied with this lecture to take the follow-up lecture and pay for it. *When I read other people's posts, they said that the explanation is fast, but it is not simply that it is difficult to understand because the explanation is fast, but I think it is lacking in the technique of matching the chart and the explanation or the explanation using cases or examples. In fact, I feel stressed the whole time I listen. I have to stop and say, "What is this?"... *I listened to this lecture while reading the Insight Java book... The topics are similar. However, the nature of this lecture is ambiguous. It does not cover a wider area than Insight Java, and it does not help you understand the core concepts that were difficult to understand with Insight Java alone... When I paid for this lecture, I expected it to be just a supplementary lecture to help you understand Insight well, but I think it fell short in that role. I should have thought that it was a waste of money and time to grasp this one concept.
Please note that this is a course review before renewal.

Great lecture It's quite different from the Java lectures I've taken so far. If most lectures start from the basics, I can say that this lecture covers the core context. Honestly, if you search for Java lectures on YouTube, you'll see a lot about variables and arrays. I recommend it because it helps students focus more on parts that they're confused about, such as callbacks and scopes, and parts that they need to think about more. In fact, since he's not a professional instructor or professor, the way he explains the lectures may seem unfamiliar. I thought it was surprisingly refreshing and good.

I can't help but agree with the statement that "If only someone had told me by poking me in the side..." I spent a lot of time studying on my own, and I want to use the time I spent to poking someone in the side. I want to give them confidence. I wanted to know why this was important while studying on my own. I was touched by the Intro in the appendix. There was a time when I studied on my own, but I gave up. Since you've been poking me in the side since the Flow lecture, I don't think I'll give up this time. Thank you.

Actually, when I listened to it when I knew nothing, I gave up halfway through. I really didn't understand it. But after getting a job and continuing to study separately, I was lost and happened to listen to it again... It was a lecture that solved the points that I had been confused about and organized them as a bonus. If there are people like me who are lost about concepts like prototype, Execute Environment, and Lexical Environment, I definitely recommend listening to it. (However, I don't recommend listening to it if you are really new to JavaScript!)
