# --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 `"No such contact"`.

If `prop` does not correspond to any valid properties of a contact found to match `name` then return `"No such property"`.

# --hints--

`lookUpProfile("Kristian", "lastName")` should return `"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 "No such contact"

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

`lookUpProfile("Bob", "potato")` should return "No such contact"

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

`lookUpProfile("Akira", "address")` should return "No such property"

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