Enhance the store with third-party capabilities such as middleware, time travel, persistence, etc.

Note about the batchedSubscribe enhancer:

When normalization is configured and enabled, action creators can end up firing multiple actions back-to-back. By default, these actions do not get batched by Redux (it notifies React that the store changed after every action), which means every action will cause React to re-render the application. When this occurs back-to-back over a very short period of time, the responsiveness (and usability) of the application can drop noticeably.

The batchedSubscribe enhancer, combined with the use of the _.debounce function, is a way of preventing this behavior, by preventing Redux from notifying React about changes to the Store until at least X time has passed between updates.

Lore sets this value to 0 by default, which translates to "one tick". This delay should be undetectable to users, but just long enough to make sure that all actions from a normalized response are processed before React is notified of the change.

enhancer: function(middleware, config) {
  return Redux.compose(
    Redux.applyMiddleware.apply(null, middleware),
    batchedSubscribe(_.debounce(function(notify) {
      notify();
    }, config.redux.debounceWait))
  );
