How can you extract a property value from a nested object using JSON parsing?

Attempting to parse a property within nested objects and an array using JSON.parse(nodeInfluxSeries). Here's the structure:

 Array [
  Object {
    "id": 1,
    "properties": Object {
      "nodeInfluxSeries": "[{\"database\": \"boba\", \"fields\": [], \"measurement\": \"boba\", \"retentionPolicy\": \"boba\", \"tags\": {\"nodeId\": \"boba\"}}]",
      "series": "",
      "version": "",
    },
    "userRights": Object {
      "monitorManagement": true,
      "propertyEdit": Object {},
    },
  },
]

Attempted the following, but it adds a new property to the first object.
note: random refers to the array

    random.map(r => {
      return {
        ...r,
        nodeInfluxSeries: JSON.parse(c.properties.nodeInfluxSeries),
      };
    })

To properly handle the data, make sure to nest the JSON.parse() method within the properties property of the outcome.

random.map(r => {
  return {
    ...r,
    properties: {
      ...r.properties,
      nodeInfluxSeries: JSON.parse(r.properties.nodeInfluxSeries)
    }
  };
})

If you prefer, you can directly update the property instead of reconstructing all the objects:

random.forEach(r => r.properties.nodeInfluxSeries = JSON.parse(r.properties.nodeInfluxSeries));
