How does WebRTC work?

WebRTC is a set of JavaScript APIs that enable real-time audio and video communication between two browsers without server intervention, reducing latency. It differs from WebSockets, which involves data exchange between the client and server. While WebRTC uses User Datagram Protocol (UDP) for fast data transmission, it lacks reliability checks and built-in signaling. To establish a connection, peers exchange Session Description Protocol (SDP) and ICE candidates. Trickle ICE is used to send ICE candidates as they are received, ensuring optimal data flow between the two peers.
