		console.log("WebSocket Opened", ev.timeStamp);
		ws.send("Hello World!");
	});

	const onError$: ErrorEventFunction = $((ev, ws) => {
		console.log("Received error");

		ws.close();
	});

	const onMessage$: MessageEventFunction = $((ev, ws) => {
		console.log("Received Message", ev.data);

		ws.close();
	});

	const onClose$: CloseEventFunction = $((ev, ws, funcs) => {
		console.log("Websocket Closed", ev.timeStamp);
		console.log(ws.readyState);

		// Events can access the additional websocket functions provided in the 3rd argument.
		funcs.reconnect();
