Yes, it is equivalent to $().attr("value") so it gets the value attribute of
the first element.

> Set the value of every matched element.
Yes, it will set a "value" attribute for each element, regardless of whether
the doctype indicates the element has a "value" attribute. Generally you'd
only want to use .val() in cases where the element responded to having a
"value" attribute though.

I think the word "works" means "makes sense" here. What should
$("div").val() return? Right now it would be undefined since usually a div
has no value attribute. I could see an interpretation where it might return
the text nodes inside the div, but $().text() already does that.
