 All created `CloudEvent` objects are read-only. If you need to update a property or add a new extension to an existing cloud event object, you can use the `cloneWith` method. This will return a new `CloudEvent` with any update or new properties. For example:
 
 ```js
-const {
-  CloudEvent,
-} = require("cloudevents");
+import { CloudEvent } from "cloudevents";
 
 // Create a new CloudEvent
