Javascript random on array without repeat [duplicate]

Answer 1

You need to write some logic. Below is one sample example.

    var list = [1, 2, 3, 4, 5];
    var listDone = [];        
    var inProcess = true;
    while(inProcess){
        var randomQuiz = Math.floor(Math.random() * list.length);

        var isDone = false;
        for (var j = 0; j < listDone.length; j++) {
            if (listDone[j] === randomQuiz)
                isDone = true;
        }
        if (!isDone) {
            console.log(list[randomQuiz]);//Display if not Done.
            listDone.push(randomQuiz);
        }

        if (list.length == listDone.length)
            inProcess = false;

    }
