--description--
We have an array of objects representing different people in our contacts lists.
A lookUpProfile
function that takes name
and a property (prop
) as arguments has been pre-written for you.
The function should check if name
is an actual contact's firstName
and the given property (prop
) is a property of that contact.
If both are true, then return the "value" of that property.
If name
does not correspond to any contacts then return the string No such contact
.
If prop
does not correspond to any valid properties of a contact found to match name
then return the string No such property
.
--hints--
lookUpProfile("Kristian", "lastName")
should return the string Vos
assert(lookUpProfile('Kristian', 'lastName') === 'Vos');
lookUpProfile("Sherlock", "likes")
should return ["Intriguing Cases", "Violin"]
assert.deepEqual(lookUpProfile('Sherlock', 'likes'), [
'Intriguing Cases',
'Violin'
]);
lookUpProfile("Harry", "likes")
should return an array
assert(typeof lookUpProfile('Harry', 'likes') === 'object');
lookUpProfile("Bob", "number")
should return the string No such contact
assert(lookUpProfile('Bob', 'number') === 'No such contact');
lookUpProfile("Bob", "potato")
should return the string No such contact
assert(lookUpProfile('Bob', 'potato') === 'No such contact');
lookUpProfile("Akira", "address")
should return the string No such property
assert(lookUpProfile('Akira', 'address') === 'No such property');
