BroadcastChannel: close() method - Web APIs | MDN (original) (raw)

Baseline

Widely available

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

Examples

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

// More operations (like postMessage, …)

// When done, disconnect from the channel
bc.close();
