Questions & Answers

Hello again great minds of stack overflow! Iam working in an angular project and my question is about mapping JSON objects. So i have JSON Object that i am taking out from html it is of the format

const obj = {
  firstLevelKey1 : "Value1",
  thirdLevelKey2 : [{
    "diffKey1": "diffValue1",
    "diffKey2" : "diffValue2",
    "diffKey3" : "diffValue3"
  },{
    "diffKey1": "diffValue1",
    "diffKey2" : "diffValue2",
    "diffKey3" : "diffValue3"
  },{
    "diffKey1": "diffValue1",
    "diffKey2" : "diffValue2",
    "diffKey3" : "diffValue3"
  }],
  thirdLevelKey3 : ["string1", "string2", "string3"]
}

the format I want to map with is like this

const objToMap = [{
  firstLevelKey1 : [{
    dataType : 'String'
  },{
    value : 'someString'
  },{
    someKey : 'someValue'
  }]
},{
  firstLevelKey2:[{
    dataType : 'Object'
  },{
    value : [{
      secondLevelKey1 :[{
        dataType : 'String'
      },{
        value : 'someString'
      },{
        someKey : 'someValue'
      }]
    },{
      secondLevelKey2 : [{
        dataType : 'Object'
      },{
        value : [{
          thirdLevelKey1:[{
            dataType : 'String'
          },{
            value : 'someString'
          },{
            someKey : 'someValue'
          }]
        },{
          thirdLevelKey2 : [{
            dataType : 'String'
          },{
            value : 'someString'
          },{
            someKey : 'someValue'
          }]
        },{
          thirdLevelKey3 : [{
            dataType : 'String'
          },{
            value : 'someString'
          },{
            someKey : 'someValue'
          }]
        }]
      },{
        someKey : 'someValue'
      }]
    },{
      secondLevelKey3 :[{
        dataType : 'String'
      },{
        value : 'someString'
      },{
        someKey : 'someValue'
      }]
    }]
  },{
    someKey : 'someValue'
  }]
},{
  firstLevelKey3 : [{
    dataType : 'String'
  },{
    value : 'someString'
  },{
    someKey : 'someValue'
  }]
}]

after getting the flattening with keyNames function from here, the great stack overflow the json object I can also generate (using innertext property)

const anotherObj = {
  "firstLevelKey1" : "firstLevelValue",
  "firstLevelKey2#secondLevlKey1" : "secondLevelValue1",
  "firstLevelKey2#secondLevelKey2#thirdLevelKey1" : "thirdLevelValue1",
  "firstLevelKey2#secondLevelKey2#thirdLevelKey2" : [{
    "diffKey1": "diffValue1",
    "diffKey2" : "diffValue2",
    "diffKey3" : "diffValue3"
  },{
    "diffKey1": "diffValue1",
    "diffKey2" : "diffValue2",
    "diffKey3" : "diffValue3"
  },{
    "diffKey1": "diffValue1",
    "diffKey2" : "diffValue2",
    "diffKey3" : "diffValue3"
  }],
  "firstLevelKey2#secondLevelKey2#thirdLevelKey3": ["string1", "string2", "string3"],
  "firstLevelKey2#secondLevelKey3" : "secondLevelValue3",
  "firstLevelKey3" : "firstLevelValue3"
}

so can I please know how do I map obj/anotherObj to objToMap, the values from obj/anotherObj should map for value key in objToMap, that is I should send it back in the same format I got in with values added in any help is greatly appreciated.
