Serving static content from port 8080?

Question

Is it a bad practice to serve JS (static content basically - css, js and images) on port 8080 instead of HTTP (80)? If so, why? If not, are there any advantages at all?

Answer 1

80 is the standard http port and mostly all firewalls are configured to allow traffic to this port. Any other port may need specific port privileges configured in firewall.
