## Description
|
|
<section id='description'>
|
|
The last few challenges showed that each object in the JSON array contains an <code>imageLink</code> key with a value that is the URL of a cat's image.
|
|
When you're looping through these objects, you can use this <code>imageLink</code> property to display this image in an <code>img</code> element.
|
|
Here's the code that does this:
|
|
<code>html += "<img src = '" + val.imageLink + "' " + "alt='" + val.altText + "'>";</code>
|
|
</section>
|
|
|
|
## Instructions
|
|
<section id='instructions'>
|
|
Add code to use the <code>imageLink</code> and <code>altText</code> properties in an <code>img</code> tag.
|
|

## Tests

|
|
```yml
|
|
tests:
|
|
- text: You should use the <code>imageLink</code> property to display the images.
|
|
testString: assert(code.match(/val\.imageLink/g));
|
|
|
|
```
