# --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`
```js
assert(lookUpProfile('Kristian', 'lastName') === 'Vos');
```
`lookUpProfile("Sherlock", "likes")` should return `["Intriguing Cases", "Violin"]`
```js
assert.deepEqual(lookUpProfile('Sherlock', 'likes'), [
'Intriguing Cases',
'Violin'
]);
```
`lookUpProfile("Harry", "likes")` should return an array
```js
assert(typeof lookUpProfile('Harry', 'likes') === 'object');
```
`lookUpProfile("Bob", "number")` should return the string `No such contact`
```js
assert(lookUpProfile('Bob', 'number') === 'No such contact');
```
`lookUpProfile("Bob", "potato")` should return the string `No such contact`
```js
assert(lookUpProfile('Bob', 'potato') === 'No such contact');
```
`lookUpProfile("Akira", "address")` should return the string `No such property`
```js
assert(lookUpProfile('Akira', 'address') === 'No such property');
```
