onWindowTitleChangedconst

onWindowTitleChange is a JavaScript event that fires when the title of a browser window or tab is modified. This event is primarily used by web developers to track changes to the document's title, which can be set and modified using the `document.title` property in JavaScript.

The `onWindowTitleChange` event is not a standard, widely supported DOM event. It is important to note that its implementation and availability can vary significantly across different web browsers and their versions. Developers often resort to alternative methods to detect title changes, such as periodically polling the `document.title` property or using Mutation Observers to watch for changes within the `<title>` element if the browser supports it.

When the event is triggered, it typically provides an event object, although the specific properties and behavior of this object are not standardized. The primary use case for detecting window title changes includes scenarios where a web application needs to update its state or trigger specific actions based on the displayed title. For instance, a web application might want to synchronize its internal state with the window title, or a browser extension might monitor title changes to perform specific actions related to the active tab. Due to its limited and inconsistent support, developers should exercise caution when relying on this event and always provide fallback mechanisms.
