BroadcastChannel.close()
This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
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
var str = channe<code>l</code><code>.close();</code>
Example
// Connect to a channel var bc = new BroadcastChannel("test_channel"); // More operations (like postMessage, …) // When done, disconnect from the channel bc.close();
