What are websockets and how do they work?

Websockets are a communication protocol that allows real-time, two-way communication between a web browser and a server. Unlike traditional HTTP requests, which follow a request/response paradigm, websockets create a persistent connection between the client and the server. This connection allows for instant and continuous communication, enabling real-time updates and data streaming without the overhead of frequent requests. Websockets work by using a handshake process when establishing a connection. Once connected, both the client and server can send and receive data asynchronously, eliminating the need for periodic polling and reducing latency. This technology has found extensive use in applications that require real-time updates, such as chat applications, multiplayer games, and financial markets.
