    address: {
      city: 'New York',
      zip: '10001',
    }

  info: {
    address: {
      city: 'New York',
      zip: '10001',
    }
  }
};

var sample_2 = {
  firstName: "Ali",
  lastName: "Parsa",
  age: 21,
  info: {
    location: {
      city: 'Canada',
      zip: '10001',
    }
  }
};

console.log(grabValue(sample_1, "info.city")) //=> 'New York'
console.log(grabPath(person, "info.city")) //=> '.info.address.city'

console.log(grabValue(sample_2, "city")) //=> 'Canada'
console.log(grabPath(person, "city")) //=> '.info.location.city'

console.log(grabValue(sample_2, "info.wrong","not found!")) //=> 'not found!'
