About
Fetch is a modern 
JavaScript API for requesting network resources and exchanging data between web applications and servers.
It provides a promise-based interface for asynchronous HTTP requests, supports streaming request and response bodies, works with service workers, and can handle data formats such as 
JSON, text, blobs, and binary content.
WebSocket is a communication protocol that enables persistent, full-duplex data exchange between a client and a server over a single TCP connection.
It maintains a long-lived connection that allows low-latency message exchange, supports both text and binary frames, minimizes overhead by avoiding repeated request headers, and enables servers to push data to clients in real time.
