--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

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

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

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

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

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

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

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

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

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

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

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