“span” or “div” elements do not have a built-in “value” property.

*That* should work, though, as the corresponding object *does* have a built-
in value property.

By contrast to the “innerHTML” property, the “textContent” property does not 
require any escaping beyond the one required for a syntactically correct 
ECMAScript program; indeed, if you HTML-escape the value assigned to it, the 
escape sequences will be displayed verbatim.
