method Server.prototype.close
Usage in Deno
import { Server } from "node:net";
Server.prototype.close(callback?: (err?: Error) => void): this
Stops the server from accepting new connections and keeps existing
connections. This function is asynchronous, the server is finally closed
when all connections are ended and the server emits a 'close' event.
The optional callback will be called once the 'close' event occurs. Unlike
that event, it will be called with an Error as its only argument if the server
was not open when it was closed.
