The wordsArrayArbitrary method is called with a string() method as an argument. The string() method is called with no arguments, so it will use the default values. The default values are:6The min and max values are the minimum and maximum length of the strings in the array, respectively. The array() method is called with no arguments. So, the default values are used, which are:
