Conditional Matches

If there is only one element in that nodeList then it doesn’t care, it just does that one item, but would be capable of doing multiple ones if they existed too.

Just curious, but how would it react if it found no matching elements?

querySelectorAll gives an empty nodeList when no matching elements are found. Using forEach on that empty nodeList doesn’t result in any error either.

When forEach is run on an empty nodeList or an empty array, it just does nothing because it has nothing to do it on.

So, no matching elements is a safe situation that occurs with no error.
