a.js

const scoo = 'doo';

console.log(module.exports === exports);

// Assign variable scoo to exports
exports.scoo = scoo;
// Assign variable scoo to module.exports
module.exports = scoo;

console.log(module.exports === exports );

b.js

const a = require('a');
console.log(a);

The question is what would the output of all the console.log from both the files, if we run this command

node b.js
