[Moo] Is there a way of extending '.getRandom' so it returns more than 1

[antonsam...@googlemail.com]

Hi guys,

does any one know if there is a script out there that will return a
given number of random elements?

Mootools has '.getRandom' but this only returns 1 random item from the
array.

I want to be able to specify the amount of random items to return e.g.

var array = [1,2,3,4,5,6,7,8,9]

var randoms = array.getRandom(5); //[5,3,7,4,8]
