is it possible to retrieve and print the data from a json object inside json array without using any index values and specific keys

[
    {
        "id": "628ba44f5a6de600071d16fa",
        "@baseType": "LogicalResource",
        "isBundle": false,
        "isMNP": false,
        "businessType": [],
        "category": [
            {
                "id": "628ba3ef5a6de600071d165f",
                "name": "Starterpack2",
                "description": "Starterpack2",
                "code": "RC17",
                "version": 2
            }}]

now i need to check and print the JSON Object inside the JSON Array if category is present then it should print and in future if category is changed according to that if we pass parameter the output should print we don’t hard code the code

i have tried by using key values it is coming but if the key value changes it is not printing the object
EX:-

[
    {
        "id": "628ba44f5a6de600071d16fa",
        "@baseType": "LogicalResource",
        "isBundle": false,
        "isMNP": false,
        "businessType": [],
        "category": [
            {
                "id": "628ba3ef5a6de600071d165f",
                "name": "Starterpack2",
                "description": "Starterpack2",
                "code": "RC17",
                "version": 2
            }}]

in the above code i have printed category object but if category changed to categories it is not printing so i want a code which can read the code and based on parameters user giving it should be print the output

    It seems you want to get the value of the key(that can be parameterized).

    const jsonArray = [
  {
    "id": "628ba44f5a6de600071d16fa",
    "@baseType": "LogicalResource",
    "isBundle": false,
    "isMNP": false,
    "businessType": [],
    "category": [
      {
        "id": "628ba3ef5a6de600071d165f",
        "name": "Starterpack2",
        "description": "Starterpack2",
        "code": "RC17",
        "version": 2
      }
    ]
  }
];

const parameter = "category";

const result = jsonArray.find(({ [parameter]: value }) => value);

if (result) {
  console.log(result);
} else {
  console.log(`No object found with ${parameter}`);
}

    Try this.

    For Example:

    let a = [{"id": "628ba44f5a6de600071d16fa","category": [
        {
            "id": "628ba3ef5a6de600071d165f",
            "name": "Starterpack2",
            "description": "Starterpack2",
            "code": "RC17",
            "version": 2
        }]}]
        
      function print (values){return (a[0][`${values}`])}

     //now just pass any name like "category" or in future "categories"

     print("category")  //this will retrun the array.

    Now modify with your requirements.
