WebSocket
A long-lived bidirectional channel for realtime communication
Core Idea
A WebSocket keeps one connection open so both client and server can send messages whenever needed. That makes it useful for chat, collaborative editing, and dashboards where the state changes constantly.
Why It Matters Here
Mathbong introduces WebSockets as the upgrade path beyond SSE and polling. They cost more to manage, but they provide the clearest realtime model when many users must stay in sync.
