Originally, I was planning to study on my own by reading the official Svelte documentation, but I happened to come across Heropy's blog while searching for Svelte, and I ended up buying the instructor's Svelte course right after listening to this lecture. I'll just write down the pros I felt from the lecture. (I don't know the cons yet because it's a short lecture.) 1. There's no unnecessary content in the video, and only the necessary content is included, so there's no time wasted. 2. The explanation is easy to understand and logical. - The flow of the explanation is good, and the instructor catches the confusing parts and explains them in detail. - The intonation is good, so important parts are emphasized audibly (Sometimes I don't pay attention to this part, so lectures that proceed in monotone cause me to fall asleep a lot..) 3. The diction is very good, so it's easy to listen to even when listening at 2x speed.
