This is not so much a limitation of the importArticles function as it is a limitation of HTTP. Every HTTP response needs to have a Content-Type header. The Content-Type tells the browser what the body of the response contains and how to process it. There's "text/javascript" (or "application/javascript") for JS and "text/css" for stylesheets. A HTTP response cannot have more than one Content-Type. So it's JS or CSS but not both.
