javascript - 在对象数组中添加位置/顺序

Question

我有一个如下所示的对象数组:

    [{
    "id": 1,
    "Size": 90,
    "Maturity": 24,
   },
  {
    "id": 2,
    "Size": 85,
    "Maturity": 22,
  },
  {
    "id": 3,
    "Size": 80,
    "Maturity": 20,
   }]

我需要根据不同的属性值排序(例如:成熟度)对此数组进行排序，并添加一个具有升序/排名的列顺序。例如:

      [{
        "id": 1,
        "Size": 90,
        "Maturity": 22,
         "Order": 2
       },
      {
        "id": 2,
        "Size": 85,
        "Maturity": 25,
        "Order": 3
      },
      {
        "id": 3,
        "Size": 80,
        "Maturity": 20,
        "Order": 1
       }]

Answer 1

const arr = [{
    "id": 1,
    "Size": 90,
    "Maturity": 24,
   },
   {
    "id": 2,
    "Size": 85,
    "Maturity": 22,
   },
   {
    "id": 3,
    "Size": 80,
    "Maturity": 20,
   }];

arr
  .map((item,index) => ({ ...item, Order: index + 1 }))
  .sort((a, b) => b.Maturity - a.Maturity)
