    three: {
      value: "this is a string",
      four: {
        value: [0, 1, 2, 3, [[0, 1, 2, 3], [3.14, 3.1416]]]
      }
    }
  }
}

const result1 = propFinder.find(object, "three")

console.log(result1)

/* Output:

{ 'two.three.value': 'this is a string' }

*/

const result2 = propFinder.findAll(
        object, "value",
        { array: true } /* If you want to flatten Array */
    )

console.log(result2)

/* Output:

{ value: 1,
  'two.value': 2,
  'two.three.value': 'this is a string',
  'two.three.four.value.0': 0,
  'two.three.four.value.1': 1,
  'two.three.four.value.2': 2,
  'two.three.four.value.3': 3,
  'two.three.four.value.4.1.0': 3.14,
