When you visit a website your browser speaks with the server in http. It is structured in requests and responses. You request a text, you get it. You request to upload an image, it is done. Very useful, but what if you wanted to get a live feed of things. Imagine you wanted to chat. You could send many requests always asking “is there a new message?” and always getting “no”. That’s not good, with a websocket your webbrowser and the server establish a live connection. Now they can send and receive small pieces of information. For chatting, games, auctions and many other things websockets are useful.
