javascript - What is the rendering engine?

Question

I saw a name like "Presentation Engine" (P229) while reading the Little Red Book today
It includes: IE, Gecko, Webkit, KHTML, Opera five major rendering engines;
I was confused immediately, and then After searching on Baidu and Zhihu, I became even more confused. . . .

Is there any difference between rendering engine, kernel, typesetting engine, rendering engine and JavaScript engine?
