how to modify properties of an nested object?

Question

I have the following nested object and I need to leave the "alias" property blank and the "group" property set to true for all "entries" and "exits". I also need to delete the whole "parameters" object. Would there be a way to do it all in one function? I've tried to apply the delete Object method but it doesn't work as it's an indexed object.

{
  "1": {
    "x": 114,
    "y": 135,
    "properties": {
      "id": 1,
      "entries": {
        "entry_0": {
          "id": 1,
          "alias": "do",
          "group": false
        }
      },
      "exits": {
        "exit_0": {
          "id": 1,
          "alias": "re",
          "group": false
        }
      },
      "parameters": {
        "parameter_0": {
          "id": 3,
          "group": false
        }
      },
      "order": 1
    }
  },
  "2": {
    "x": 700,
    "y": 104,
    "properties": {
      "id": 1
      "entries": {
        "entry_0": {
          "id": 1
          "alias": "do"
          "group": false
        }
      },
      "exits": {
        "exyt_0": {
          "id": 1
          "alias": "re"
          "group": false
        }
      },
      "parameters": {
        "parameter_0": {
          "id": 3
          "alias": "mi"
          "group": false
        }
      },
      "order": 2
    }
  }
}

the desired nested object would be the following

{
  "1": {
    "x": 114,
    "y": 135,
    "properties": {
      "id": 1,
      "entries": {
        "entry_0": {
          "id": 1,
          "alias": "",
          "group": true
        }
      },
      "exits": {
        "exit_0": {
          "id": 1,
          "alias": "",
          "group": true
        }
      },
      "order": 1
    }
  },
  "2": {
    "x": 700,
    "y": 104,
    "properties": {
      "id": 1
      "entries": {
        "entry_0": {
          "id": 1
          "alias": ""
          "group": true
        }
      },
      "exits": {
        "exyt_0": {
          "id": 1
          "alias": ""
          "group": true
        }
      },
      "order": 2
    }
  }
}

what I've tried is the following, managing to delete the "parameters" object but I can't access the "label" property of each "entry" and "exit

const nedtedObjectsValues = Object.values(nestedObjects);
for (object of nedtedObjectsValues) {
   delete object.properties.parameters;

}

if anyone can give me an idea of how to approach this function. Thank you in advance.

In JavaScript, to reference numeric object properties, you need to use the square brackets syntax:

object.1 // bad
object[1] // good

You can delete numeric property like this:

delete object[1];
