...because i cannot imagine from which place we received a data in our key (main) function of this lesson.

The ".className" property of an element will contain all the class names assigned to that element. Is that what you were asking in the first question?

But I don't quite understand the 2nd question, could you rephrase and/or elaborate a bit?

Yes, sorry, but where is this class names, assigned to that element? When i wrote " li.className " in console.log, i dont see nothing. second is about this function: if (li.className === 'responded') { li.style.display = ' '; } else { li.style.display = 'none'; } Thanks.

I can't be sure without seeing the whole code, but perhaps the element doesn't have any class name(s) assigned to it, and so the property is empty.
