Select all li elements than call the remove method on element at index 0;

let listItems = document.querySelectorAll('li');
listItems[0].remove();

If you wish to use "removeChild", you need to apply the method to the parent, and supply the child as the argument:

myList.removeChild(firstListItem);

In actual practice, you could also use the "remove" method, applied directly to the element being removed. But the challenge only accepts the method that was introduced in the course.
