title: Testing Objects for Properties
challengeType: 1
---

## Description
<section id='description'>
Sometimes it is useful to check if the property of a given object exists or not. We can use the <code>.hasOwnProperty(propname)</code> method of objects to determine if that object has the given property name. <code>.hasOwnProperty()</code> returns <code>true</code> or <code>false</code> if the property is found or not.
<strong>Example</strong>
<blockquote>var myObj = {<br>&nbsp;&nbsp;top: "hat",<br>&nbsp;&nbsp;bottom: "pants"<br>};<br>myObj.hasOwnProperty("top");    // true<br>myObj.hasOwnProperty("middle"); // false</blockquote>
</section>

## Instructions
<section id='instructions'>
Modify the function <code>checkObj</code> to test <code>myObj</code> for <code>checkProp</code>. If the property is found, return that property's value. If not, return <code>"Not Found"</code>.
</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: <code>checkObj("gift")</code> should return  <code>"pony"</code>.
    testString: 'assert(checkObj("gift") === "pony", "<code>checkObj("gift")</code> should return  <code>"pony"</code>.");'
  - text: <code>checkObj("pet")</code> should return  <code>"kitten"</code>.
    testString: 'assert(checkObj("pet") === "kitten", "<code>checkObj("pet")</code> should return  <code>"kitten"</code>.");'
  - text: <code>checkObj("house")</code> should return  <code>"Not Found"</code>.
    testString: 'assert(checkObj("house") === "Not Found", "<code>checkObj("house")</code> should return  <code>"Not Found"</code>.");'

```
