NextJS Global Variable with Assignment

Question

I'm new to NextJS, and trying to figure out, how to create a global variable that I could assign a different value anytime. Could someone give a simple example? (I know global might not be the best approach, but still I would like to know how to set up a global variable).

Let's say:

_app.js

NAME = "Ana" // GLOBAL VARIABLE

page_A.js

console.log(NAME) // "Ana"
NAME = "Ben"

page_B.js

console.log(NAME) // "Ben"

Nextjs no special ways to provide global variables you want. You can achieve by:

1. Stateful management tool, like redux-react
2. Using Context
