## Description
<section id='description'>
У нас есть набор объектов, представляющих разные люди в наших списках контактов. Функция <code>lookUpProfile</code> которая принимает <code>name</code> и свойство ( <code>prop</code> ) в качестве аргументов, была предварительно написана для вас. Функция должна проверять, является ли <code>name</code> фактическим контактом <code>firstName</code> и данное свойство ( <code>prop</code> ) является свойством этого контакта. Если оба они истинны, верните «значение» этого свойства. Если <code>name</code> не соответствует контактам, тогда верните <code>&quot;No such contact&quot;</code> Если <code>prop</code> не соответствует каким-либо действительным свойствам контакта, найденного для соответствия <code>name</code> тогда верните <code>&quot;No such property&quot;</code>

```yml
tests:
  - text: <code>"Kristian", "lastName"</code> should return <code>"Vos"</code>
    testString: assert(lookUpProfile('Kristian','lastName') === "Vos");
  - 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");
