Define what functions you would prefer that currently depend on a message channel Open
Please give an example code that uses a message sent from a previous page via a service worker or the BroadcastChannel API:
“`javascript
// Define a handler for receiving messages
function messageEvent(event) {
// Print the message to the console
console.log(event.data);
}
// Attach the handler to the user-visible page
window.addEventListener(‘message’, messageEvent, false);
“`
The code receives messages from a previous page via the BroadcastChannel API and the `message` event is handled to log the incoming data to the console.
