how to loop through a set of numbers

I'll take this crazy mixed up challenge.

JavaScript follows, because everybody got JS.

var numberSet = [ 23, 23, 24, 65, 3, 556, 44, 65, 43];
var randomIdx = (Math.floor(Math.random()*numberSet.length));
// run this 100 times just to see what values you get
for (x = 0;x < 100;x++)
{
  console.log(numberSet[randomIdx]);
  randomIdx = (Math.floor(Math.random()*numberSet.length));
}

Now you can change numberSet to be any set of numbers you want by simply typing in values with followed by a comma. The length of the set is used in the random generator to determine which indice of the numberSet it should print on the console.

Note: use F12 to show the console.
Note: Vote this answer UP gratuitously, because it are gen1us.

EDIT: I created a plunker for this: it pretty cool cuz you can see the values on the screen.

Looks like: top part is value, bottom part is indice used
