Class syntax comes from those who want to fit JS in their plastic class-oriented boxes, it seems.
Anyway, I was in the process of working on a library to authenticate users through Discord before I started reading the book. And at the time, I thought classes would be the way to go to neatly write it all out, particularly because of the whole module system. However, after reading the book, I decided to start over. Instead of taking the class approach, I'm taking the OLOO approach, and already, I'm having a much better time building this thing.
