# --description--

Tenemos un arreglo de objetos que representan a diferentes personas en nuestras listas de contactos.

Una función `lookUpProfile` que recibe nombre (`name`) y una propiedad (`prop`) como argumentos preescritos para ti.

La función debe verificar si el nombre (`name`) es el nombre de pila del contacto (`firstName`) y la propiedad (`prop`) dada es una propiedad de ese contacto.

Si ambos son verdaderos, entonces devolver el "valor" de esa propiedad.

Si `name` no corresponde a ningún contacto, entonces devuelve la cadena `No such contact`.

Si `prop` no corresponde a ninguna propiedad válida de un contacto encontrado que coincida con `name` entonces devuelve la cadena `No such property`.

# --hints--

`lookUpProfile("Kristian", "lastName")` debe devolver la cadena `Vos`

```js
assert(lookUpProfile('Kristian', 'lastName') === 'Vos');
```

`lookUpProfile("Sherlock", "likes")` debe devolver `["Intriguing Cases", "Violin"]`

```js
assert.deepEqual(lookUpProfile('Sherlock', 'likes'), [
  'Intriguing Cases',
  'Violin'
]);
```

`lookUpProfile("Harry", "likes")` debe devolver un arreglo

```js
assert(typeof lookUpProfile('Harry', 'likes') === 'object');
```

`lookUpProfile("Bob", "number")` debe devolver la cadena `No such contact`

```js
assert(lookUpProfile('Bob', 'number') === 'No such contact');
```

`lookUpProfile("Bob", "potato")` debe devolver la cadena `No such contact`

```js
assert(lookUpProfile('Bob', 'potato') === 'No such contact');
```

`lookUpProfile("Akira", "address")` debe devolver la cadena `No such property`

```js
assert(lookUpProfile('Akira', 'address') === 'No such property');
```
