const myList = document.getElementsByTagName('li');
for ( let i = 0; i < myList.length; i += 1 ) { myList[i].style.color = 'red'; }

The reason we write script tags as the last element(s) before the closing body tag is to ensurre that the browser has loaded all the DOM elements it needs before it looks for the JavaScript. That should rule out any exceptions for elements that don't yet exist on browser load.
