This is interesting when you want near realtime performances, as you don't have all the culprint of a http request : you basically just send a few octets (a json document, or even just a simple value), and you don't have to build a request and negotiate a connection.
This is not something obvious because we have helpers to make http requests, but there are many things going on while issuing a http request (building headers, encoding body, etc) [1]. A socket (be it a websocket or a classic socket) has this advantage that all the negotiating part is already done and you just have to send the message, in whatever format you want. Decoding the request on server side is way easier too.
