About
PerformanceObserver is a part of the Performance API that is used to monitor performance measurement events.
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.
