BroadcastChannel allows scripts from the same origin but other browsing contexts (windows, workers) to send each other messages. By making a BroadcastChannel question, which is tuning in to the hidden channel, you can get any message that has been presented on it. An intriguing point is that you never again need to keep up a reference to iframes or specialists that you wish to speak with. They can just "buy in" to specific channels by building a BroadcastChannel, and have full-duplex (bi-directional) correspondence between every one of them.
