test.js file;

let k = 0;
let set = () => {
    k = 1;
};
export { k, set };

test1.js file;

import { k, set } from './test.js';

set();
console.log(k); // --> k = 1;

but

test.js file;

let k = 0;
let set = () => {
    k = 1;
};
module.export = { k, set };

test1.js file;

let { k, set } = require('./test.js');

set();
console.log(k); // --> k = 0;

What is the reason for this behavior?

Functionally, shouldn’t the k value be 1?
