I had put the code into description, it was in the title. I hope there was some actual difficulty and simply wasn't an attempt to get a badge or an upvote.

My effort...
Basically write a random number generator which returns the array index from 0 to last element in the array.

//code below
var items =[523, 3452, 334, 31, 5346]
items[Math.floor(Math.random() * (items.length))]
