Good catch!

I removed the duplicate setAttribute call and kept img.src, as it already sets the image source correctly.

This simplifies the implementation while maintaining the expected HTML output for the tests.


// Add image to list item
li.appendChild(img);

// Set background colour based on read status
if (book.alreadyRead) {
li.style.backgroundColor = "green";
} else {
li.style.backgroundColor = "red";
}

// Add to page
list.appendChild(li);
});
