Передача значений из объекта в массив - Javascript

Question

Ниже моя попытка, у меня есть объект, который имеет массив объектов внутри него, у него есть поле: 'positionTitle'.

У меня также есть массив объектов, который также имеет 'positionTitle'

Они оба имеют схожие данные. Я хочу, чтобы все значения для positionTitles в моих индивидуальных данных помещались в графические данные и теперь могли использовать эти новые графические данные!

Я думаю, что моя попытка ошибочна, я считаю их обоих массивами?

Спасибо, Дейл

graphData = {
  "engagementAreas": [{
    "id": "1",
    "engagementTypes": [{
        "name": "forestry",
        "engagements": []
      },
      {
        "name": "houses",
        "engagements": [{
          "name": "engagement1",
          "members": [{
            "position": {
              "id": "3434",
              "positionTitle": "Manager"
            }
          }]
        }]
      }
    ]
  }]
}, {
  "name": "landscaping",
  "engagements": [{
    "name": "engagement1343",
    "members": [{
      "position": {
        "id": "4545",
        "positionTitle": "Senior Manager"

      }
    }]
  }]
}

IndividualData = [{
  "account": {
    "id": "001b000003WnPy1AAF",
    "fullName": "Adnan A. Khan"
  },
  "positions": [{
    "id": "a16b0000004AxeBAAS",
    "organizationId": "001b0000005gxmlAAA",
    "organizationName": "a",
    "positionTitle": "Senior Manager, Energy",
    "positionLevel": "5-Middle Management & Advisers",
    "isPrimary": true,
    "startDate": "2016-10-07",
    "endDate": null
  }]
}, {
  "account": {

  "positions": [{

    "isPrimary": true,
    "startDate": "2018-03-05",
    "endDate": null
  }]
}

What I expect to see:  

 NEWgraphData = {
  "engagementAreas": [{
    "id": "1",
    "engagementTypes": [{
        "name": "forestry",
        "engagements": []
      },
      {
        "name": "houses",
        "engagements": [{
          "name": "engagement1",
          "members": [{
            "position": {
              "id": "3434",
              "positionTitle": "Senior Manager, Energy" <== from individualsdata
            }
          }]
        }]
      }
    ]
  }]
}, {
  "name": "landscaping",
  "engagements": [{
    "name": "engagement1343",
    "members": [{
      "position": {
        "id": "4545",
        "positionTitle": "Managing Director" <== also from individuals data

      }
    }]
  }]
}

graphData.engagementAreas.map((el, i) => {
  el.engagementTypes.engagements.members.position.positionTitle = individualsData.positions.positionTitle;
  return el;
})

const updateMembers = members => members.map(member => {
  const position = allPositions.find(pos => pos.id === member.position.id) || {

const updatedEngagementAreas = graphData.engagementAreas.map(updateEngagementTypes);

console.log('UpdatedEngagementAreas mapped based on position id', updatedEngagementAreas)
