Return value
A String representing a random suit of length characters picked from preset.
Description
This method generates a string of length random characters chosen from either a preset or a custom string of characters.
If the preset parameter is not defined, the default preset used will be safe, which is a mix of letters and numerals minus characters that could be confused for one another (e.g. l for I, 0 for O …).
For alphabet characters, the method will discretely decide to randomly convert them from lower to upper case or not.
Examples
Generate a random string of 50 characters
monster.util.randomString(50);
// output: '8F5GN8kr6gyTRuKAjG53Rxms644QVEn3dyUcyPJb5k93g2CvHF'
Generate a random string of 4 numerals
monster.util.randomString(4, 'numerals');
// output: '0986'
Generate a random string of 10 custom characters
monster.util.randomString(10, '!@#$%^&*()_+{}|:"<>?~`-=[]\;\',./');
// output: ']/{]#=&!:;'
