我想分享解决这个问题的百万种方法之一=）

function shuffleArray(array = ["banana", "ovo", "salsicha", "goiaba", "chocolate"]) {
const newArray = [];
let number = Math.floor(Math.random() * array.length);
let count = 1;
newArray.push(array[number]);

while (count < array.length) {
    const newNumber = Math.floor(Math.random() * array.length);
    if (!newArray.includes(array[newNumber])) {
        count++;
        number = newNumber;
        newArray.push(array[number]);
    }
}

return newArray;

}

// 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];
    })
}

函数shuffleArray（数组）{//在参数中创建具有给定数组长度的新数组const newArray=array.map（（）=>null）；//创建一个新数组，其中每个索引都包含索引值const arrayReference=array.map（（项，索引）=>索引）；//对参数中给定的数组进行迭代array.forEach（随机化）；return newArray；函数随机化（项）{const randomIndex=getRandomIndex（）；//替换新数组中的值newArray[arrayReference[randomIndex]]=项；//在数组引用中删除使用的索引arrayReference拼接（randomIndex，1）；}//返回介于0和当前数组引用长度之间的数字函数getRandomIndex（）{常量最小值=0；const max=arrayReference.length；return Math.floor（Math.random（）*（max-min））+min；}}控制台日志（shuffleArray（[10,20,30,40,60,70,80,90100]）；

可以（但不应该）将其用作Array中的原型：

来自ChristopheD：

Array.prototype.shuffle = function() {
  var i = this.length, j, temp;
  if ( i == 0 ) return this;
  while ( --i ) {
     j = Math.floor( Math.random() * ( i + 1 ) );
     temp = this[i];
     this[i] = this[j];
     this[j] = temp;
  }
  return this;
}

var shuffledArray = function(inpArr){
    //inpArr - is input array
    var arrRand = []; //this will give shuffled array
    var arrTempInd = []; // to store shuffled indexes
    var max = inpArr.length;
    var min = 0;
    var tempInd;
    var i = 0;

    do{
        //generate random index between range
        tempInd = Math.floor(Math.random() * (max - min));
        //check if index is already available in array to avoid repetition
        if(arrTempInd.indexOf(tempInd)<0){
            //push character at random index
            arrRand[i] = inpArr[tempInd];
            //push random indexes
            arrTempInd.push(tempInd);
            i++;
        }
    }
    // check if random array length is equal to input array length
    while(arrTempInd.length < max){
        return arrRand; // this will return shuffled Array
    }
};

只需将数组传递给函数，然后得到经过洗牌的数组

费希尔·耶茨在javascript中洗牌。我在这里发表这篇文章是因为与这里的其他答案相比，使用两个实用函数（swap和randInt）澄清了算法。

function swap(arr, i, j) { 
  // swaps two elements of an array in place
  var temp = arr[i];
  arr[i] = arr[j];
  arr[j] = temp;
}
function randInt(max) { 
  // returns random integer between 0 and max-1 inclusive.
  return Math.floor(Math.random()*max);
}
function shuffle(arr) {
  // For each slot in the array (starting at the end), 
  // pick an element randomly from the unplaced elements and
  // place it in the slot, exchanging places with the 
  // element in the slot. 
  for(var slot = arr.length - 1; slot > 0; slot--){
    var element = randInt(slot+1);
    swap(arr, element, slot);
  }
}
