When using getElementById() or getElementsByClassName you do not need the # or '.' prefix as we already know it is an Id or a class that we want to get, so we just need the text after the prefix.

So in your code example, if you update it as below:

let myList = document.querySelector('ul');
let firstListItem = document.getElementById('first');
myList.removeChild(firstListItem);

you should now be OK, hope this helps :)
