Question

我正在寻找一种功能性的解决方案，将这个对象映射到一个层次结构中，按实践，主题区和资产分组，以便这个对象：

var data = {
  "research": [
    { "practice": "Talent Management", "id": "20992", "title": "Creating a Culture of Leadership", "subjectArea": "Talent Strategy" },
    { "practice": "Talent Management", "id": "20993", "title": "Talent Economics", "subjectArea": "Talent Strategy" },
    { "practice": "Talent Management", "id": "20990", "title": "Finding the Right Talent", "subjectArea": "Recruiting" },
    {  "practice": "Human Resources", "id": "20994", "title": "Tips from the Front", "subjectArea": "HR Training" },
    { "practice": "Human Resources", "id": "20995", "title": "Reward Programs", "subjectArea": "Employee Engagement" },
  ]
}

转换为此（计算练习的项目数量，并将练习的主题区域添加为儿童，计算练习中主题区域的项目数量，并将资产（ID和标题）添加为子项对于主题领域）：

{
  "name": "research",
    "children": [
      {
        "name": "Talent Management", "size": 3, "children": [
          {
            "name": "Talent Strategy", "size": 2, "children": [
              { "name": "Creating a Culture of Leadership", "id": "20992", "size": 1 },
              { "name": "Talent Economics", "id": "20993", "size": 1 }
            ]
          },
          {
            "name": "Recruiting", "size": 1, "children": [
              { "title": "Finding the Right Talent", "id": "20990", "size": 1 },
            ]
          }
        ]
      },
      {
        "name": "Human Resources", "size": 2, "children": [
          {
            "name": "HR Training", "size": 1, "children": [
              { "name": "Tips from the Front", "id": "20994", "size": 1 },
            ]
          },
          {
            "name": "Employee Engagement", "size": 1, "children": [
              { "name": "Reward Programs", "id": "20995", "size": 1 },
            ]
          }
        ]
      }, 
    ]  
}

我无法整理地图并减少组合以使用计数产生正确的结果，并欣赏任何洞察力。

它可能不是SO的原因（根据上面的评论），但是如果有人需要将平面对象数组转换为层次结构，您只需指定嵌套顺序，级别数和字段名称，这是一个递归函数 - https://github.com/lance-p/configurable-transform-flat-array-to-nested。希望它可能对其他人有帮助。
