重写后的标题为：将三个数组合并为类似树形结构的数据

Question

如果我有以下数据如下：

var data = [{

        },
        {

            children: [{
                    "EmployeeID": 6,

                },
                {
                    "EmployeeID": 7,
                    "FirstName": "Robert",
                    "LastName": "King",

                    "BirthDate": "1960-05-29 00:00:00",
                    "City": "London",
                    "Address": "Edgeham Hollow Winchester Way"
                },
                {
                    "EmployeeID": 9,
                    "FirstName": "Anne",
                    "LastName": "Dodsworth",

                    "City": "London",
                    "Address": "7 Houndstooth Rd."
                }
            ]
        }
    ]
}];

console.log(data);

对于每个父级的children属性，我有单独的Ajax调用，它们会返回一个数组。是否可能将这三个数组组合起来，生成一个如fiddle中所示的数组？

以上数据的原始来源是这里，这是从这里获取的

我想要的更多解释：

我手头有3个数组。

1. 一个数组中包含"EmployeeID": 2,的数据。
2. 第二个数组包含"EmployeeID": 8,1,3,4和5，是第一个数组的子项。
3. 第三个数组包含"EmployeeID": 6,7和9，是第二个数组的子项。

我通过Ajax调用获取了以上所有数组（未在上面显示），想知道是否可以以这种方式组合它们，以生成上述格式的数据。 让我困惑的是如何像上面的格式中那样添加children: 。

在这里你可以尝试这个逻辑：
我们可以传递具有嵌套结构的数据，例如：
data->childrenArray->data->childrenArray等等在MakeNestedInLinear(data)中，它将返回单个数组（线性数据）中的扁平结果
