WebSockets are a tool for bidirectional communication between a browser client and a server. In particular, WebSockets enable the server to push data to the client. This is different from your standard HTTP request using fetch() or Axios because the server cannot communicate with the client unless the client sends a request first.. WebSockets are more flexible, but also are harder to implement

Technically, the WebSocket protocol is initiated as an upgrade of an HTTP request. This implies, that a connection needs to be initiated by a client. Once the WebSocket connection is established after the upgrade request, both partners act as peers. The connection becomes a full-duplex communication. Every peer may send data at any time.
