I am a complete beginner who just wanted to code my own website with a designer base. I only had prior knowledge of HTML/CSS and studied JavaScript briefly at Codecademy, but I couldn't remember it well (I didn't think I understood the concepts clearly), so I decided to take a basic lecture and purchased the course. If you look at the lecture itself, you might think that the lecture time is very short, but in that short time, important concepts are explained so clearly that you won't need to ask questions. It is explained so cleanly that you really won't need to ask questions. I personally think that even beginners who don't know anything about JavaScript will get a lot of help if they start. (When I looked at books for beginners in JavaScript such as e-books, I felt like the concepts were really firmly established in my head with the short lectures, even though I didn't understand them at all. Also, when reviewing after coding, I looked at the O'Relly JavaScript Rhinoceros book again, and when I read while comparing the parts explained by the teacher with the keynote, I felt like the concepts were firmly established, so it was very helpful.)
In my case, when I was reviewing on my own, I used post-its and such to cover up the coded parts as the teacher said, and I tried coding on my own, and at the same time, I practiced JavaScript separately at Codecademy and continued coding on my own. I think it's because the basics were so well laid out that there were no parts that I didn't understand and stopped in the middle. (I thought, "Isn't it difficult?" but the explanation was so easy to understand that I thought, "Why is this difficult?" several times. Haha) And I was also turned upside down by gag points such as ramen here and there. (It may be just my taste, but I thought it would be boring at first, but guess what... there were so many parts that made me laugh out loud because of the comments he made here and there.) What's really amazing is that when Professor Kim Young-bo explains a concept, I think about which situation and which code I can use it with, and when implementing something like this, I think about whether I can use this code, and when I look at other people's code, I feel like I've gained the ability to understand the code itself, like I'm using it in this situation (I guess it's not just repetitive learning, but implementing the code while thinking about it). I'm very satisfied because the professor shared many valuable experiences and even small details that he realized in the practical part. However, in order to properly utilize this lecture, as the professor said in the first lecture, I need to practice and review my personal coding experience properly so that it can be utilized as knowledge that remains in my head. (i.e. listening to the lecture - covering the coding part in the keynote with a piece of paper and proceeding on your own - if you get it wrong, think about what you did wrong rather than looking at the answer - if you don't understand the concept, listen to the lecture again (or compare it to other JavaScript books and review the concept again and organize it) - repeat coding... Simply watching the lecture is not something that will stay in your head no matter how good the lecture is.)
I can't believe that such a high-quality lecture can be kept for 5 years and costs 30,000 won. Thank you so much for sharing your valuable knowledge, teacher.
