How is the theme of growing up explored in Night by Elie Weisel?

I've never read it. But heres what I found on the internet for it.

Wiesel had to grow up quickly, struggling to understand himself, his situation and his religion, the very faith that thrust him into the middle of the Holocaust. Night explores how the loss of family and identity can lead to questioning of faith, and how horrific situations can push children into adulthood.

Elie, at the age of 15 had his rights stripped and had only his father to be with him for a short period of time. Elie had to grow up and mature faster than most boys his age because of the holocaust
