I tried like this

Answer 1

You want to append to user_data not the whole object another object

Try using the array notation

data["user_data"]["name"] = "tom";

or

data.user_data.name = "tom";

demo:

data = {"user_data": {
    "_id": "5806319c08756025b4c7287b",
    "email": "[email protected]",
    "password": "cool123",
  }};
  
  data["user_data"]["name"] = "tom";
  console.log(data)

Answer 2

simply)

  o = {
    "_id": "5806319c08756025b4c7287b",
    "email": "[email protected]",
    "password": "cool123",
  }

and then

o.name = "tom"
