Prototypes are a primitive data type of Javascript (a basic building block). Classes are not offered natively and have to be constructed with lower level building blocks such as prototypes. This is why classes are said to be higher level than prototypes in Javascript. Does that help?

Do you think that is the sense of the word "Primitive" intended by the author of JSX? In that sense of the word, what does "More" primitive or "Too primitive" mean? I would have thought something was either a primitive or it wasn't- not a sliding scale.
