// Create a places array which holds the index for each item in the
// passed in array.
// 
// Then return a new array by randomly selecting items from the
// passed in array by referencing the places array item. Removing that
// places item each time though.
function shuffle(array) {
    let places = array.map((item, index) => index);
    return array.map((item, index, array) => {
      const random_index = Math.floor(Math.random() * places.length);
      const places_value = places[random_index];
      places.splice(random_index, 1);
      return array[places_value];
    })
}

使用array.splice（）随机化数组

function shuffleArray(array) {
   var temp = [];
   var len=array.length;
   while(len){
      temp.push(array.splice(Math.floor(Math.random()*array.length),1)[0]);
      len--;
   }
   return temp;
}
//console.log("Here >>> "+shuffleArray([4,2,3,5,8,1,0]));

// places item each time though.
function shuffle(array) {
    let places = array.map((item, index) => index);
    return array.map((item, index, array) => {
      const random_index = Math.floor(Math.random() * places.length);
      const places_value = places[random_index];
      places.splice(random_index, 1);
      return array[places_value];
    })
}

随机化数组，无重复项

    function randomize(array){
        let nums = [];
        for(let i = 0; i < array.length; ++i){
            nums.push(i);
        }   
        nums.sort(() => Math.random() - Math.random()).slice(0, array.length)
        for(let i = 0; i < array.length; ++i){
            array[i] = array[nums[i]];
        }
    }
    randomize(array);

为了更灵活，可以添加另一个参数。在这种情况下，可以从数组中获取一个随机数组，并指定新数组的长度：

  function shuffle(array, len = array.length) {
        for (let i = array.length - 1; i > 0; i--) {
            let j = Math.floor(Math.random() * (i + 1));
            [array[i], array[j]] = [array[j], array[i]];
        }

        return array.slice(0, len);
    }

d3.js提供了Fisher–Yates shuffle的内置版本：

console.log（d3.shuffle（[“a”，“b”，“c”，“d”]）；<script src=“http://d3js.org/d3.v5.min.js“></script>

d3.洗牌（array[，lo[，hi]]）<>使用Fisher–Yates混洗随机化指定阵列的顺序。
