# --description--

Temos um array de objetos representando pessoas diferentes nas nossas listas de contatos.

Uma função `lookUpProfile`, que recebe `name` e uma propriedade (`prop`) como argumentos, foi pré-escrita para você.

A função deve verificar se `name` é o `firstName` (primeiro nome) de um contato e se a propriedade passada (`prop`) é uma propriedade daquele contato.

Se ambos forem verdadeiros, então retorne o "valor" daquela propriedade.

Se `name` não corresponder a nenhum dos contatos, então retorne a string `No such contact`.

Se `prop` não corresponder a nenhuma propriedade válida de um contato encontrado para coincidir com `name` então retorne a string `No such property`.

# --hints--

`lookUpProfile("Kristian", "lastName")` deve retornar a string `Vos`

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

`lookUpProfile("Sherlock", "likes")` deve retornar `["Intriguing Cases", "Violin"]`

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

`lookUpProfile("Harry", "likes")` deve retornar um array

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

`lookUpProfile("Bob", "number")` deve retornar a string `No such contact`

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

`lookUpProfile("Bob", "potato")` deve retornar a string `No such contact`

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

`lookUpProfile("Akira", "address")` deve retornar a string `No such property`

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