   当用户点击了“Crisis Center”链接或者在地址栏粘贴`localhost:3000/crisis-center/`时，我们更希望该应用能直接显示危机列表。这就是默认路由。

   A redirect route requires a `pathMatch` property to tell the router how to match a URL to the path of a route.

   由于我们希望只有在路径明确的匹配到`''`时才重定向，所以我们往路由中添加了一个额外的配置项：`terminal: true`。

-    The other possible `pathMatch` value is `'prefix'` which tells the router 
-    to match the redirect route to _any_ URL that _begins_ with the redirect route's _prefix_ path.
+    Technically, `pathMatch = 'full'` results in a route hit when the *remaining*, unmatched segments of the URL match `''`. 
+    In our example, the redirect is at the top level of the route configuration tree so the *remaining* URL and the *entire* URL
+    are the same thing.
 
-    That's not what we want in our use case. The `''` prefix path matches _every_ URL.
-    We should redirect to the `CrisisCenterComponent` _only_ when the _entire_ url is  `''` 
-    (or the equivalent `'/'`).

+    That's not what we want to do here. If the `pathMatch` value were `'prefix'`,
