Webpack renames variables in imports

[jeanid]

It's a problem.

tab.js contains such data:

let qwerty = 'qwerty'

scripts.js contains:

'use strict';
import 'tab.js'
console.log('qwerty', qwerty);

As a result, a mistake is made on the page:

Uncaught ReferenceError: qwerty is not defined

I looked in a computerized file and I see it:

'use strict';

let tab_qwerty = 'qwerty';

console.log('qwerty', qwerty);

Renamed the variable qwerty Total tab_qwertyso the variable that I want is inaccessible.
How do you think?

In fact, three articles had to be very careful. https://learn.javascript.ru/modules

tab.js

export let qwerty = 'qwerty'

scripts.js

import {qwerty} from 'tab.js'
