One more point I'd like to add, useRef can be used for storing any value that you might need later on, in class component you can use this.something to access any variable everywhere. but in functional component you can't. so useRef can be used anywhere.
one more point, that in useEffect if you want to know what was the previous state before updating the new state, then only useRef can be used no other way around.

It is not suggested to directly manipulate Dom in react. React handles all the dom manipulation for you

Class components have render method but function components doesn't have render method they return elements. Why?
