UpperCasedCharacters.sort(() => Math.random() - 0.5) LowerCasedCharacters.sort(() => Math.random() - 0.5) RandomNumbers = numericCharacters.sort(() => Math.random() - 0.5) Let allArrays = //included allArrays locally (instead of globally) so we don't have to reload the page to generate another password Function for getting a random element from an array
