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

Answer 1

    var array = [];

    setInterval(function(){

        if(array .length === 0){ 
            reload(); 
        }

        var result = getRandom();

        console.log(result);

    },1000);

    function getRandom(){
        var index = (array.length === 1 ? 0 : Math.floor(Math.random() * array.length));
        return array.splice(index, 1)[0];
    }

    function reload(){
        array = [2,3,4,5,6,7,8,9,0,1,44,66];
    }
