Is there any issue with using for of loops instead of the basic for loop?

I solved the filter checkbox problem like this:

filterCheckBox.addEventListener('change', (e) => {
  const isChecked = e.target.checked;
  const lis = ul.children;
  if (isChecked) {
    for (each of lis)
      if (each.className === 'responded') {
        each.style.display = '';
      } else {
        each.style.display = 'none';
      }
  } else {
    for (each of lis) {
      each.style.display = ''; 
    }
  }
});

I felt that for of loops were neater and quicker to write. Is there any problems with this approach?

Thanks!

As you discovered, it's an effective and concise approach, so you're likely just getting ahead of things. Unless for ... of was introduced earlier in this same course, it was probably not used to avoid any confusion.
