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
js
channel.close()
js
// Connect to a channel
const bc = new BroadcastChannel("test_channel");
// More operations (like postMessage, …)
// When done, disconnect from the channel
bc.close();
