使用ES2015，您可以使用此功能：

Array.prototype.shuffle = function() {
  let m = this.length, i;
  while (m) {
    i = (Math.random() * m--) >>> 0;
    [this[m], this[i]] = [this[i], this[m]]
  }
  return this;
}

用法：

[1, 2, 3, 4, 5, 6, 7].shuffle();

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);

我发现这很有用：

const shuffle = (array: any[]) => {
    return array.slice().sort(() => Math.random() - 0.5);
  }
        
console.log(shuffle([1,2,3,4,5,6,7,8,9,10]));
// Output: [4, 3, 8, 10, 1, 7, 9, 2, 6, 5]

// 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];
    })
}

重建整个阵列，逐个将每个元素放在一个随机位置。

[1,2,3].reduce((a,x,i)=>{a.splice(Math.floor(Math.random()*(i+1)),0,x);return a},[])

变量ia=[1,2,3]；var it=1000；var f=（a，x，i）=>｛a.splice（Math.floor（Math.random（）*（i+1）），0，x）；返回a｝；var a=新数组（it）.fill（ia）.map（x=>x.reduce（f，[]））；var r=新数组（ia.length）.fill（0）.map（（x，i）=>a.reduce（（i2，x2）=>x2[i]+i2,0）/it）console.log（“这些值应该相当相等：”，r）；

 const arr = [
  { index: 0, value: "0" },
  { index: 1, value: "1" },
  { index: 2, value: "2" },
  { index: 3, value: "3" },
];
let shuffle = (arr) => {
  let set = new Set();
  while (set.size != arr.length) {
    let rand = Math.floor(Math.random() * arr.length);
    set.add(arr[rand]);
  }
  console.log(set);
};
shuffle(arr);
