WebRTC or Web Real-Time Communications, though a relatively new web technology, has taken web-based communication at an entirely new level with the promise of heralding into a brave new world of communication on the horizon. The free, open-source WebRTC project makes use of a set of JavaScript APIs to facilitate peer-to-peer communication between web browsers and different devices. The question remains what makes it so popular.
A big draw with WebRTC is it eliminates the use of plugins or third-party software to facilitate real-time communication, helping achieve the ultimate goal of moving in a plugin-free world.
