BroadcastChannel
The BroadcastChannel interface represents a named channel that any browsing context of a given origin can subscribe to.
Functions
The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.
The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order.
The postMessage() method of the BroadcastChannel interface sends a message, which can be of any kind of Object, to each listener in any browsing context with the same origin.
The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener() from the target.
