NavigationCurrentEntryChangeEvent
The NavigationCurrentEntryChangeEvent interface of the Navigation API is the event object for the currententrychange event, which fires when the currentEntry has changed.
This event will fire for same-document navigations (e.g., back() or traverseTo()), replacements (i.e., a navigate() call with history set to replace), or other calls that change the entry’s state (e.g., updateCurrentEntry(), or the History API’s replaceState()).
This event fires after the navigation is committed, meaning that the visible URL has changed and the NavigationHistoryEntry update has occurred. It is useful for migrating from usage of older API features like the hashchange or popstate events.
