No, it's not. If you want just the text, use textContent or innerText
as appropriate depending on which property the host supports (some
support both).

There are many other inconsistencies, mostly related to attributes as
far as I remember, so likely not important in this case but still a
good reason to avoid innerHTML for reading from the DOM in anything
other than trivial cases.

They are completely different things that do much the same job.
innerText is an IE proprietary property that has been copied by some
other browsers, textContent is a W3C DOM 3 property:
innerText property:

Consider instead:
var text;
if (typeof elem.textContent == 'string') {
text = elem.textContent;
} else if (typeof elem.innerText == 'string') {
text = elem.innerText;
}
But that will fail in certain cases in some browsers. I think the only
really reliable method is to recurse over the descendant elements and
extract the text (which in the case of a node with only one or two
text nodes as children is pretty fast).

It depends on how robust the OP wants the function to be.
