FCL-Web by itself does not create bandwidth hogs. It does not tell you what
to send to the browser. So All depends on what you do with fcl-web.
Javascript is not something you can avoid. People have come to expect a
certain functionality from a website, which can only be delivered with
Javasvript. If you don't provide it, your product will not sell.
It's as simple as that.
That said, Javascript is not all bad;
Depending on what you do, it can actually save you a lot of bandwidth by
saving complete page reloads.
