WebRTC
WebRTC (Web Real-Time Communication) is an open-source project and set of APIs that enables real-time peer-to-peer communication directly between web browsers and mobile applications. It provides audio, video, and data sharing capabilities without requiring plugins or additional software, using JavaScript APIs to facilitate low-latency connections. It is widely used for video conferencing, live streaming, file transfer, and other interactive web applications.
Developers should learn WebRTC when building applications that require real-time communication, such as video chat apps, online gaming, remote collaboration tools, or IoT device control. It is particularly valuable because it reduces server load and latency by enabling direct peer-to-peer connections, making it ideal for scenarios where performance and privacy are critical, like secure messaging or live broadcasting.
