Pros of this class: 1. Friendly code // You can see how the code is made by writing intuitive and understandable code. 2. Friendly lecture // Even if you study hard on your own, you can find out what you missed through the lecture. It explains the overall flow so that it is easy to understand. 3. A lot of interaction information // This is what I like the most. You can implement numerous interactions just by watching this lecture. The code is composed of jQuery, which is a bit disappointing, but I think it is an advantage rather than a disadvantage because it is practice in converting jQuery to JavaScript. Lastly, thank you for preparing such a great class.
