我想在使用find查询之后，将子类别作为json对象追加到父类别中。

Question

I have parent categories and child categories in my database as shown            below.
[{
"name": "electronics"
  , "parent": "/"
  , "category": "/electronics"
}, {
"name": "embedded"
  , "parent": "/electronics"
  , "category": "/electronics/embedded"
},
{
"name": "laptops"
  , "parent": "/electronics"
  , "category": "/electronics/laptops"
},
{
    "name": "dell"
  , "parent": "/electronics/laptops"
  , "category": "/electronics/laptops/dell"
},
{
    "name": "acer"
  , "parent": "/electronics/laptops"
  , "category": "/electronics/laptops/acer"

},

 {
    "name": "cases"
  , "parent": "/"
  , "category": "/cases"
}, {
"name": "big"
  , "parent": "/cases"
  , "category": "/cases/big"
}, {
"name": "small"
  , "parent": "/cases"
  , "category": "/cases/small"
}]

I want those category to be fetched by appending the child category       with the parent category as json object . ie
[electronics:{
  name:embedded
},
{
name:laptops{
name:dell
},{
name:acer
},
},
cases:{
name:big
},{
name:small
}
]

我已经使用正则表达式获取了数据，但是这些数据并没有像预期的那样出现。

我希望这些类别出现在嵌套的json对象中，如above.The所示，子类别应该附加到相应的父类别中。

我的解决方案是：

let newCategory={name:'abc'};
let data = listCategory;
listCategory.push(newCategory);
listCategory.save();
