--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

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

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

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

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

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

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

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

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

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

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

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