BroadcastChannel class

The interface represents a named channel that any browsing context of a given origin can subscribe to. It allows communication between different documents (in different windows, tabs, frames or iframes) of the same origin. Messages are broadcasted via a message event fired at all objects listening to the channel. Note: This feature is available in Web Workers
