This app is developed to learn the basics of portals and ref's in react

React portals

Portals needs two things:

1. You need a place you want to port the component to.
2. Let that component know it should have portal to that place. To mark that place we got to index.html file, add a div with id.

useRef

They allow us get access to other DOM elements n work with them.

How do refs work?
With refs we can set up connection b/w a HTML element which is being rendered in the end & our other Javascript code.

What does useRef return & what value it takes?
It takes default value you wanna initialize it to, it returns value which allows us to work with that ref later.

If you just want to read a value refs are probably better than state.
