Finding highest count by sum up of an attribute in an Json array in javascript

Question

I'm looking for clean and efficient way to get highest value count by sum up of all attributes in following json array.

[{ "id":1, "material":2, "noMaterial":3, "negative":1 }, { "id":2, "material":4, "noMaterial":3, "negative":3}, { "id":3, "material":0, "noMaterial":1, "negative":1}]

Expected Output:

{ "noMaterial": 7 }

I defined a reusable hook that you can use on other attributes of your array as follows:

function getSum(keyName, data) {
  return {[keyName]: 
    data.reduce((acc, current) => {
      return acc + current[keyName]; 
    }, 0)
  };
}

and then call apply it on your data as follows:

getSum("noMaterial", data);
