BroadcastChannel()

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() constructor creates a new BroadcastChannel and connects it to the underlying channel.

Note: This feature is available in Web Workers.

Syntax

Values

var bc = new BroadcastChannel("internal_notification");
bc.postMessage("New listening connected!");
