BroadcastChannel: close() method

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

Syntax

js

channel.close()

Example

js

// Connect to a channel
const bc = new BroadcastChannel("test_channel");

// More operations (like postMessage, …)

bc.close();
