Ways to eliminate a targeted key within a JSON reply

Ways to eliminate a targeted key within a JSON reply

I'm working with a JSON response in postman and need to figure out how to remove a specific key from the data. In this case, I want to remove head_out_timestam - no matter where it is in the object tree.

This needs to be done using javascript. Any help is greatly appreciated!

{
 "soapenv:Envelope": {
      "$": {
          "xmlns:soapenv": "http://schemas.xmlsoap.org/soap/envelope/"
    },
      "soapenv:Header": {
          "f:Routing": {
              "f:Receiver": {
                  "f:Application": "Something"
            }
        }
    },
      "soapenv:Body": {
          "Something": {
              "something_output": {
                  "service_header_out": {
                      "head_out_servercode": "Some",
                      "head_out_timestam": "2019-06-18-11.32.13.570127",
                }
            }
        }
    }
}

}

Answer №1

To efficiently remove a specific key from an object, you can perform a recursive search for the key and then delete it once found.

Consider the following approach:

var data = {
"user1": {
    "name": "John",
    "age": 30
},
"user2": {
    "name": "Jane",
    "age": 25
}
}

var removeKey = (data, target) => {
  Object.keys(data).forEach((key) => {
    if (key === target) {
      delete data[key];
    } else if (typeof data[key] === 'object') {
      removeKey(data[key], target);
    }
  });
  return data;
}

console.log(removeKey(data, 'age'));

Note: You have the option to utilize Object.keys(obj).forEach or for ... in loops for iterating through objects.
