Random String Generator

var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890'; const setCharacters = charactersToUse => { characters = charactersToUse; }

const randomString = length => { var returnStr = ""; for (var i = 0; i < characters.length; i++){ returnStr += characters(Math.floor(Math.random() * characters.length)); } return returnStr; }

const twoRandoms = length => { return nRandoms(2, length); }

const nRandoms = (n, length) => { var outputArray = []; for (var i = 0; i < n; i++){ outputArray.push(randomString(length)); } return outputArray; }
