The Problem

Let’s consider a sample case where you’re attempting to log the id of each YouTube video from a JSON array. The code snippet below illustrates the common mistake leading to this error:

[[See Video to Reveal this Text or Code Snippet]]

Breaking Down the Solution

To solve this issue, let’s walk through the correct steps to access the id for each item in the JSON array:

Step 1: Understand the JSON Structure

The provided JSON array is structured as follows:

[[See Video to Reveal this Text or Code Snippet]]

Step 2: Access the Correct Property

To correct the code, you need to access the id property of each item in the array. This is done by updating the console log statement:

[[See Video to Reveal this Text or Code Snippet]]

Step 3: Run the Code

After this change, you should now see the correct id values logged in the console without any errors. This adjustment accurately iterates through each video object, retrieving the id property.
