It’s usually used to create real-time web applications, social network feeds, PWA and push notifications, chats, etc. In Ubuntu based distributions, for example, you can use a websocket server that will have a thread to every amount of time, refresh some data and trigger a new event, making system-calls to the notify-send program, which will show you a notification in your desktop.
