; a [i] = a [j]; a [j] = x; } 返回a; } 此算法以相反的順序通過數組迭代，將每個元素與數組前面的隨機元素交換。 The resulting array is shuffled due to the random nature of the swaps.

Usage

The shuffle function can be used to shuffle an array using the following syntax:

es6版本

function shuffle(a) {
    var j, x, i;
    for (i = a.length - 1; i > 0; i--) {
        j = Math.floor(Math.random() * (i   1));
        x = a[i];
        a[i] = a[j];
        a[j] = x;
    }
    return a;
}

此實現允許使用arr.shuffle（）語法將數組改組。 [&& &&&&華
