Just use Object.keys method.

The Object.keys() method returns an array of a given object's own enumerable properties, in the same order as that provided by a for...in loop (the difference being that a for-in loop enumerates properties in the prototype chain as well).

const keys = Object.keys(diagnosis)

You can use Object.keys. For more info see this

var diagnosis= {
  "type": [],
  "kode": [],
  "PrimaryCat": [],
  "Location": [],
  "Encountrace": [],
  "Fracture": [],
  "Healing": [],
}

var keys=Object.keys(diagnosis);
console.log(keys)
