arrayGenerator.js

const fs = require('fs')

const createArray = ({ length }) => Array.from({ length }, (_, i) => i + 1); // [1, 2, 3, ...]

    Array.from(Array(length)).map(() => Math.random() * 10)

const string = `module.exports = [${[...createLargeArray(), 122]}]`

fs.writeFile('largeArray.js', string, (error => {
    if (error) throw error
    console.log('Created a large array!')
