--description--

The last few challenges showed that each object in the JSON array contains an imageLink key with a value that is the URL of a cat's image.

When you're looping through these objects, you can use this imageLink property to display this image in an img element.

Here's the code that does this:

js
html += "";

--instructions--

Add code to use the imageLink and altText properties in an img tag.

--hints--

You should use the imageLink property to display the images.

js
assert.match(code, /val\.imageLink/g);

You should use the altText for the alt attribute values of the images.

js
assert.match(code, /val\.altText/g);
