WebRTC vs WebSockets

Question: Compare WebRTC and WebSockets -- what are the pros and cons of each?

Expected discussion: WebSockets provide a persistent, full-duplex TCP connection between client and server, ideal for client-server real-time messaging (chat, notifications) but all traffic still flows through the server. WebRTC enables direct peer-to-peer connections (audio/video/data) using ICE/STUN/TURN for NAT traversal, reducing server load and latency for media streaming, but is more complex to set up and typically still needs a signaling server (often built on WebSockets) to negotiate the connection.
