 Returns `true` or `false` depending on if the `pathnameOrLoc` is active. Will be true for every route in the route branch matched (child route is active, therefore parent is too), unless `onlyActiveOnIndex` is specified, in which case it will only match the exact path.

 ##### `children`
 Routes can be nested, `this.props.children` will contain the element created from the child route component. Please refer to the [Route Configuration](/docs/guides/basics/RouteConfiguration.md) since this is a very critical part of the router's design.
 
-##### `onEnter(nextState, replaceState, callback?)`
+##### `onEnter(nextState, replace, callback?)`
 Called when a route is about to be entered. It provides the next router state and a function to redirect to another path. `this` will be the route instance that triggered the hook.
 
 If `callback` is listed as a 3rd argument, this hook will run asynchronously, and the transition will block until `callback` is called.

 If an enter hook needs to execute asynchronously, it may list a 3rd `callback` argument that it must call in order to cause the transition to proceed.
 
 **Caution:** Using the `callback` in an enter hook causes the transition to wait until it is called. **This can lead to a non-responsive UI if you don't call it very quickly**.

-A *router* is a [`history`](http://rackt.github.io/history) object (akin to `window.history` in web browsers) that is used to modify and listen for changes to the URL.
-
-There are two primary interfaces for computing a router's next [state](#routerstate):
-
-- `history.listen` is to be used in stateful environments (such as web browsers) that need to update the UI over a period of time. This method immediately invokes its `listener` argument once and returns a function that must be called to stop listening for changes
-- `history.match` is a function that does not update the history's internal state. This makes it ideal for server-side environments where many requests must be handled concurrently

-A *router listener* is a function that is used to listen for changes to a [router](#router)'s [state](#routerstate).
