When stepping through the `recognize` algorithm, it is much easier to follow when using a simple `for...of` rather than the helper `mapChildrenIntoArray` with the passed closure. The only special thing that `mapChildrenIntoArray` does is ensure the primary route appears first. This change will have no affect on the result because `processChildren` later calls `sortActivatedRouteSnapshots`, which does the same thing. PR Close #40029
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.
