Search string in nested array of objects and return matched objects as result

Question

I have the array of objects as input shown below. This has property vertical as type string, platformList is an array and radar_metadata is nested object

I want to search for a string and get those object which has string value in it. Its like a search functionality that i am trying to implement.

let input = [
 {
    "vertical": "Partner",
    "platformList": [
      "Access"
    ],
    "radar_metadata": {
      "state": "Verify",
    }
  },
 {
    "vertical": "Integration",
    "platformList": [
      "Identity"
    ],
    "radar_metadata": {
      "state": "Closed",
    }
  }
]

So i implemented this function to loop through the object elements and get those object whose string matches or is included in the object.

const filterByValue = (array, string) => {
    return array.filter((o) =>
      Object.keys(o).some((k) =>
        o[k].toString().toLowerCase().includes(string.toLowerCase())
      )
    );
  };

When i get this result1, i search for Partner text in the array of object and i get the result as follows.

let result1 = filterByValue(input, 'Partner')
----Output----
result1 = [
 {
    "vertical": "Partner",
    "platformList": [
      "Access"
    ],
    "radar_metadata": {
      "state": "Verify",
    }
  }
]

Now the complexity increases when i want to search for Ident text or Clos text. Because these searches are to be performed in nested object (radar_metadata) as well as array (platformList)

let result2 = filterByValue(input, 'Ident')
let result3 = filterByValue(input, 'Clos')
----Output----
result2 = [
 {
    "vertical": "Integration",
    "platformList": [
      "Identity"
    ],
    "radar_metadata": {
      "state": "Closed",
    }
  }
]

result3 = [
 {
    "vertical": "Integration",
    "platformList": [
      "Identity"
    ],
    "radar_metadata": {
      "state": "Closed",
    }
  }
]

Can someone let me know how to modify my filterByValue function to include these scenarios too.

You can do this by destrcturing your object:

    const filterByValue = (array, string) => {
        return array.filter((obj)=>{
        // destructure your obj to extract the data
        const {vertical, platformList, radar_metadata: {state}} = obj;
        // make an array from the destructured data
        const data = platformList.concat(state,vertical);
        // return if string is included
        return data.some( (el)=>el.toLowerCase().includes(string.toLowerCase()) );
        });
    };
