In my code, I am trying to detected if the last clicked on element is a form element where setting its name attribute would be appropriate.

What I've written works:

    const tag = lastElement.tagName;
    if (tag === "INPUT" || tag === "TEXTAREA" || tag === "SELECT") {
      ...
    }

But I am wondering if there is a more robust/elegant way to do this, like

    if (lastElement instanceof FormFieldElement) {
      ...
    }

Is there such a common class?
