I don't know how proxmox does their browser configuration. I did a
little custom stuff with kvm through a web browser and I actually used
VNC through the web browser. TightVNC comes with a java applet which you
can use through the web browser. It doesn't use javascript but I think
your web browser does have to have the java runtime plugin functional.
Proxmox may have used javascript to do some things but I don't think you
have to use it to serve your machines through a web browser. They
probably used it to do more advanced stuff than what I did as far as a
web interface is concerned, mine was pretty plain.
