	const result = await fetch(url).json()

	if(result.name == `xgqfrms`) {
		alert('You are awesome!')
	} else {
		alert('You are awesome too!')
	}
})();

Backend

#!/usr/bin/env python
import asyncio as io
import websockets as ws

async def hello(websocket, path):
		name = await websocket.recv()
		greeting = f"Hello {name}!"
		await websocket.send(greeting)

server = ws.serve(hello, 'localhost', 1337)
io.get_event_loop().run_until_complete(server)
io.get_event_loop().run_forever()
