Code will not work

I keep getting this error message for my last line of code: Uncaught SyntaxError: Unexpected end of input

addItemButton.addEventListener('click', () => { let ul = document.getElementsByTagName('ul')[0];
let li = document.createElement('li'); li.textContent = addItemInput.value; ul.appendChild('li'); addItemInput.value = ' '; });

This snippet doesn't explain that particular error, there's likely a problem elsewhere in the code (it's always a good idea to share all the code, preferably as a link to a snapshot of your workspace).

But one issue that stands out is that variable names should never be enclosed in quotes:

   ul.appendChild(li);   // not 'li'

Okay, thanks! I went back through and re-watched a video and fixed everything.
