In the new behavior Angular cleanups `popstate` and `hashchange` event listeners when the root view gets destroyed, thus event handlers are not added twice when the application is bootstrapped again. BREAKING CHANGE: Methods of the `PlatformLocation` class, namely `onPopState` and `onHashChange`, used to return `void`. Now those methods return functions that can be called to remove event handlers. PR Close #31546 PR Close #40867
Angular Router
Managing state transitions is one of the hardest parts of building applications. This is especially true on the web, where you also need to ensure that the state is reflected in the URL. In addition, we often want to split applications into multiple bundles and load them on demand. Doing this transparently isn’t trivial.
The Angular router is designed to solve these problems. Using the router, you can declaratively specify application state, manage state transitions while taking care of the URL, and load components on demand.
