Personally, I don't see why you would do this.

But if you really need to replace all the appendChild() with one statement, you can assign the outerHTML of the created elements to the innerHTML of the li element.

You just need to replace the following:

  listElement.appendChild(listItem);
  listItem.appendChild(listItemCheckbox);
  listItem.appendChild(listItemLabel);
  listItem.appendChild(editButton);
  listItem.appendChild(deleteButton);

With the following:

listItem.innerHTML+= listItemCheckbox.outerHTML + listItemLabel.outerHTML + editButton.outerHTML + deleteButton.outerHTML;
listElement.appendChild(listItem);

Explanation:

The outerHTML attribute of the element DOM interface gets the serialized HTML fragment describing the element including its descendants. So assigning the outerHTML of the created elements to the innerHTML of the li element is similar to appending them to it.
