BroadcastChannel: close() method
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2022.
Note: This feature is available in Web Workers.
The close()
method of the BroadcastChannel
interface 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.
Syntax
js
close()
Examples
js
// Connect to a channel
const bc = new BroadcastChannel("test_channel");
// More operations (like postMessage, …)
// When done, disconnect from the channel
bc.close();
