How to pass const value from one react js file to another?

Question

I am a little new on react. How can I pass a variable with its value from one react js file to another?

File A.js:

const [value, setValue] = useState(35)  

File B.js:

import value from "./A.js"
console.log(value)

Answer 1

You have to export it either as a default or a regular export.

Try the following:

export const ...

or:

export default const ...

Answer 2

In file a.js // source file

Add this:

export const endpoint_val = 'value of endpoint';

Go to file b.js

import { endpoint_val } from './a.js'
