special function to create simple-codes (eg, sms validators or coupons)

genRandomCodes.js

const randomstring = require('randomstring');
const badWords = require('./profanity.js'); // array to get the "black-list"

function genRandomCodes(quantity, length) {
  const codes = new Set();

  while (codes.size <= quantity) {
    let code = randomstring.generate(length, true);

    // This conditional is the ´code´ when this contains profane language
    if (!badWords.some(word => code.toLowerCase().includes(word))) {
      codes.add(code);
    } else {
      continue;
    }
  }

  return codes
}

for (let item of genRandomCodes(1, 6)) console.log(item + ','); // this is the "output" using shell and csv format

after create all codes, you can split using next command:

split -l 4 -d --numeric-suffixes=1 --suffix-length=3 codes.txt codes.
