What does the " span.textContent = text " works here?
const span = document.createElement('span'); span.textContent = text li.appendChild(span)
text is whatever text/string value that was passed into the createLI function.
span.textContent = text;
is effectively creating this:
<span>Text that was passed to the function</span>
is what will actually adds the span element to the page.
I hope that helps.
Stay safe and happy coding!
