Re: Idiom to return 0 or random number of array elementsby bart (Canon) |

If the second parameter for the .. operator is lower than the first parameter, then you'll get no items. BTW this will not return a random number of random elements. Instead it'll return the first N elements where N is a random number. If you want random elements, you could shuffle the array first.
