import { deno } from "https://deno.land/x/denoversion@v1.0.2/lib/lib.deno_runtime.d.ts";
const { listen } = deno;
Listen announces on the local network address.
The network must be tcp, tcp4, tcp6, unix or unixpacket.
For TCP networks, if the host in the address parameter is empty or a literal
unspecified IP address, listen() listens on all available unicast and
anycast IP addresses of the local system. To only use IPv4, use network
tcp4. The address can use a host name, but this is not recommended,
because it will create a listener for at most one of the host's IP
addresses. If the port in the address parameter is empty or 0, as in
127.0.0.1: or [::1]:0, a port number is automatically chosen. The
addr() method of Listener can be used to discover the chosen port.
See dial() for a description of the network and address parameters.
