## Description
<section id='description'>
We have an array of objects representing different people in our contacts lists.
A <code>lookUpProfile</code> function that takes <code>name</code> and a property (<code>prop</code>) as arguments has been pre-written for you.
The function should check if <code>name</code> is an actual contact's <code>firstName</code> and the given property (<code>prop</code>) is a property of that contact.
If both are true, then return the "value" of that property.
If <code>name</code> does not correspond to any contacts then return <code>"No such contact"</code>.
If <code>prop</code> does not correspond to any valid properties of a contact found to match <code>name</code> then return <code>"No such property"</code>.

## Tests
<section id='tests'>
```yml
tests:
- text: <code>"Kristian", "lastName"</code> should return <code>"Vos"</code>
testString: assert(lookUpProfile('Kristian','lastName') === "Vos", '<code>"Kristian", "lastName"</code> should return <code>"Vos"</code>');
- text: <code>"Sherlock", "likes"</code> should return <code>["Intriguing Cases", "Violin"]</code>
testString: assert.deepEqual(lookUpProfile("Sherlock", "likes"), ["Intriguing Cases", "Violin"]);
- text: <code>"Harry","likes"</code> should return an array
testString: assert(typeof lookUpProfile("Harry", "likes") === "object");
- text: <code>"Bob", "number"</code> should return "No such contact"
testString: assert(lookUpProfile("Bob", "number") === "No such contact");
- text: <code>"Bob", "potato"</code> should return "No such contact"
testString: assert(lookUpProfile("Bob", "potato") === "No such contact");
- text: <code>"Akira", "address"</code> should return "No such property"
testString: assert(lookUpProfile("Akira", "address") === "No such property");
