My solution beforehand adding the remove fn to the attached buttons

Although it's great to know that I can manipulate the children through bubbling, I added remove.addEventListener('click', () => {list.removeChild(li);} ) inside the attach fn instead for simpler readability.

// fn to add del button to every item on the list
const AddDelButton = (li) => {
    let remove = document.createElement('button');
    remove.addEventListener('click', () => {list.removeChild(li);} ) // this
    remove.className = 'remove';
    remove.textContent = 'Remove';
    li.appendChild(remove);
}

It's a bit of a tradeoff, since a single delegated handler might simplify debugging.

Plus, once you get more accustomed to using them, delegated handlers won't seem any more complicated than individual ones when reading the code.
