The read-only property returns a DOMString, which uniquely identifies the given channel with its name. This name is passed to the BroadcastChannel() constructor at creation time and is therefore read-only.

Note: This feature is available in Web Workers.


var str =;


// Connect to a channel
var bc = new BroadcastChannel('test_channel');

// More operations (like postMessage, …)

// Log the channel name to the console
console.log(; // "test_channel"

// When done, disconnect from the channel
