我有这样一个沉重的阵列:

[
  {Id: 1, Name: 'Red', optionName: 'Color'}, 
  {Id: 2, Name: 'Yellow', optionName: 'Color'},
  {Id: 3, Name: 'Blue', optionName: 'Color'},
  {Id: 4, Name: 'Green', optionName: 'Color'},
  {Id: 7, Name: 'Black', optionName: 'Color'},
  {Id: 8, Name: 'S', optionName: 'Size'},
  {Id: 11, Name: 'M', optionName: 'Size'},
  {Id: 12, Name: 'L', optionName: 'Size'},
  {Id: 13, Name: 'XL', optionName: 'Size'},
  {Id: 14, Name: 'XXL', optionName: 'Size'}
]

我需要做的是将它们分组optionName并在主数组中有两行,如下所示:

[
  {
    Name: 'Color',
    Data:[{Id: 1, Name: 'Red'},
          {Id: 2, Name: 'Yellow'},
          {Id: 3, …

我有这样的 JSON 对象：

[{
    "name" : "cat",
    "value" : 17,
    "group" : "animal",
},
 {
    "name" : "dog",
    "value" : 6,
    "group" : "animal",
},
 {
    "name" : "snak",
    "value" : 2,
    "group" : "animal",
},
{
    "name" : "tesla",
    "value" : 11,
    "group" : "car",
},
{
    "name" : "bmw",
    "value" : 23,
    "group" : "car",
}]

我想通过 JS 将此 JSON 转换为以下格式：

[{
  "name":"animal",
  "children":[
     {"name":"cat", "value":17},
     {"name":"dog", "value":6},
     {"name":"snak", "value":2}
]},
{
  "name":"car",
  "children":[
     {"name":"bmw", "value":11},
     {"name":"tesla", "value":23} …

使用一系列对象，例如：

const arr = [
  {name: "qewregf dqewafs", value: "qewregf dqewafs answer", count: 2},
  {name: "survey with select", value: "survey with select answer", count: 2},
  {name: "werasd", value: "Donald", count: 1},
  {name: "werasd", value: "Jim", count: 1}
];

我正在尝试减少name键的匹配值上的数组，并实现所需的输出，例如：

desiredOutput = [
  {name: "qewregf dqewafs", data: [{value: "qewregf dqewafs answer", count: 2}]},
  {name: "survey with select", data: [{value: "survey with select answer", count: 2}]},
  {name: "werasd", data: [{value: "Donald", count: 1}, {value: "Jim", count: 1}]}
]

这种尝试减少了数组，但是我不知道如何在不覆盖的情况下合并嵌套值。
