* @description
*
* This base route reuse strategy only reuses routes when the matched router configs are
* identical. This prevents components from being destroyed and recreated
* when just the route parameters, query parameters or fragment change
* (that is, the existing component is _reused_).
*
* This strategy does not store any routes for later reuse.
*
* Angular uses this strategy by default.
*
*
* It can be used as a base class for custom route reuse strategies, i.e. you can create your own
* class that extends the `BaseRouteReuseStrategy` one.
