quick and dirty password generator

gen.js

'use strict'

const fs = require('fs')
const words = fs.readFileSync('/usr/share/dict/words', 'utf8').split('\n')
const passwords = []
for (let i = 0; i < 12; i++) {
  const randomNumber = Math.floor(Math.random() * words.length)
  passwords.push(words[randomNumber])
}
console.log(passwords.join('-'))

You could also do something like replace s with $, o with 0, e with 3, etc..
