The `applyRedirects` and `recognize` algorithms have the same overall goal: match a `UrlTree` with the application's `Routes` config. There are a few key functions in these algorithms which can be shared rather than duplicated between the two. This also makes it easier to see how the two are similar and where they diverge.

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.
