const { log } = console;
// ⭐ use "require", not "import" (in Node)
const utils = require('./utils.js');
log(utils.power); // 9001
log(utils.square(5)); // 25
// ⭐ can also do the same thing like so:
const {power, square} = require('./utils.js');
log(power); // 9001
log(square(5)); // 25
📁 utils.js
module.exports = {
power: 9001,
square: x => x*x
};
