The language is entirely uninteresting; what's interesting is what the runtime allows you to do. Browsers purposefully don't allow you to create raw TCP connections, yet JavaScript can in many other contexts (e.g node.js) create raw sockets perfectly fine.

Which is ridiculous, as it literally brings zero advantage to restrict that.

Well I think it's a good idea to prevent web pages from just opening up a socket to some server, speaking whatever protocol they like. It could be easily abused to spam, etc.

There is, however, https://www.w3.org/TR/tcp-udp-sockets/ - see section 10 for an example.

Considering the move proposed in this thread to move even SMTP to HTTP, how would preventing connecting to SMTP prevent spam when one can still POST to SMTP-over-HTTP?
