JavaScript I'm not able to isolate my alert message to a specific image using an index reference to the array. Any thoughts?

Hey Craig! Looks like you’re close to the solution. 😊 To make each alert specific to the image clicked, you can pass an index to your myFunction to pull the correct message from the array. Here’s how:

Updated HTML​

Update each &lt;img&gt; tag to pass a unique index:

Code: 
<img src="black.circle.png"    onclick="myFunction(0)" />

<img src="red.triangle.png"    onclick="myFunction(1)" />

<img src="blue.square.png"    onclick="myFunction(2)" />

Updated JavaScript​

In JavaScript, use that index to select the right message:

Code: 
<script>    var myShapes = [        "This is a black circle image",        "This is a red triangle image",        "This is a blue square image"    ];    function myFunction(index) {          alert(myShapes[index]);      }  </script>

Explanation​

Each onclick now passes a unique index (0, 1, or 2) to myFunction, allowing it to pull the correct message from the myShapes array. This way, each alert will match the image clicked.

Hope that helps—let us know if it works! 😊
