How can I make a random array with no repeats?

Question

I\'ve been searching around for some answers to this issue, but nothing seems to work when I try to find a solution.

What I\'m trying to achieve is to make a spinner

It looks like you already have an array of the possible values. In this case you can simply shuffle the array and go through it. JavaScript doesn't have a built in shuffle function, but its pretty simple to implement.

Here is an example of a Fisher–Yates shuffle

function shuffle(array) {
  for(var i = array.length; i > 1; i--) {
    var r = Math.floor(Math.random() * i);
    var temp = array[r];
    array[r] = array[i-1];
    array[i-1] = temp;
  }
}
