The BroadcastChannel.close() terminates the connection to the underlying channel, allowing the object to be garbage collected. This is a necessary step to perform as there is no other way for a browser to know that this channel is not needed anymore.
Note: This feature is available in Web Workers
channel.close();
// Connect to a channel var bc = new BroadcastChannel('test_channel'); // More operations (like postMessage, …) // When done, disconnect from the channel bc.close();
