javascript - 如何对对象数组进行排序？

Question

我有一个包含专辑的对象数组，我想在用户重新打开专辑屏幕时对其进行随机播放。

所以我写了一些函数，但它只有一个项目而不是全部，那么我如何处理它以在洗牌后返回所有项目？

专辑

"data": [
    {
      "id": 3,
      "name": "01- Out Life 2002",
      "company": "arabic rap",
      "avatar": "upload/Albums/1579652663.jpg",
      "artists_id": 3,
      "users_id": 1,
      "created_at": "2020-01-22 00:24:23",
      "updated_at": "2020-01-23 18:20:53"
    },
    {
      "id": 1,
      "name": "02 - First 2 Bomb - 2003",
      "company": "arabic rap",
      "avatar": "upload/Albums/1579803681.jpg",
      "artists_id": 3,
      "users_id": 1,
      "created_at": "2020-01-07 01:36:35",
      "updated_at": "2020-01-23 18:21:21"
    },
    {
      "id": 5,
      "name": "Scormix 1",
      "company": "arabic rap",
      "avatar": "upload/Albums/1580658846.jpeg",
      "artists_id": 4,
      "users_id": 1,
      "created_at": "2020-02-02 15:54:06",
      "updated_at": "2020-02-02 15:54:06"
    },
]

  shuffle = arr => arr[Math.floor(arr.length * Math.random())]; 

  // just return One Item ~_~

您的函数仅返回使用随机整数访问的一项，但您可以使用 Array.map()从参数一创建一个新数组!

大概您只想将每个专辑显示一次，所以我建议 excellent answer提到Fisher-Yates shuffle的类似问题
