Right here is my drawback, I obtain these sort of json knowledge and I do not know prematurely the keys (unknownProperty#) however the completely different objects on this knowledge array have the identical keys. What I must do is to calculate the variety of every degree of alert (these ranges are fastened).
Here’s what my finish end result ought to appear to be

var end result = { unknownProperty1: { unknown: 0, okay: 2, warning: 0, ko: 1 },
  unknownProperty2: { unknown: 0, okay: 0, warning: 2, ko: 1 },
  unknownProperty3: { unknown: 3, okay: 0, warning: 0, ko: 0 },
  unknownProperty4: { unknown: 0, okay: 0, warning: 3, ko: 0 },
  unknownProperty5: { unknown: 0, okay: 0, warning: 2, ko: 1 } }

My script is working however I wish to know if there may be any strategy to optimize/clear it with map/cut back/filter javascript perform

const knowledge = [
  {
    unknownProperty1: { alert: "ok", unusedItem1: "something" },
    unknownProperty2: { alert: "warning", unusedItem1: "something" },
    unknownProperty3: { alert: "unknown", unusedItem1: "something" },
    unknownProperty4: { alert: "warning", unusedItem1: "something" },
    unknownProperty5: { alert: "ko", unusedItem1: "something" }
  },
  {
    unknownProperty1: { alert: "ok", unusedItem1: "something" },
    unknownProperty2: { alert: "warning", unusedItem1: "something" },
    unknownProperty3: { alert: "unknown", unusedItem1: "something" },
    unknownProperty4: { alert: "warning", unusedItem1: "something" },
    unknownProperty5: { alert: "warning", unusedItem1: "something" }
  },
  {
    unknownProperty1: { alert: "ko", unusedItem1: "something" },
    unknownProperty2: { alert: "ko", unusedItem1: "something" },
    unknownProperty3: { alert: "unknown", unusedItem1: "something" },
    unknownProperty4: { alert: "warning", unusedItem1: "something" },
    unknownProperty5: { alert: "warning", unusedItem1: "something" }
  }
];

var end result = new Object();
var dataKeys = knowledge.map(perform(ingredient) {
  return Object.keys(ingredient);
});
dataKeys[0].map(perform(ingredient) {
  end result[element] = { unknown: 0, okay: 0, warning: 0, ko: 0 };
});
//At this level the result's like what we anticipate however no calculation has been made but

//We then increment the appropriate values
knowledge.map(perform(ingredient) {
  for (var prop in ingredient) {
    if (Object.prototype.hasOwnProperty.name(ingredient, prop)) {
      // ingredient correspond to the present object
      // prop corresponds to the title of the important thing, for instance 'unknownProperty1'
      swap (ingredient[prop].alert) {
        case "okay":
          end result[prop].okay++;
          break;
        case "warning":
          end result[prop].warning++;
          break;
        case "unknown":
          end result[prop].unknown++;
          break;
        case "ko":
          end result[prop].ko++;
          break;

        default:
          break;
      }
    }
  }
});
console.log(end result);
