-is called and its payload, the reducer will update redux state with relevant
-changes. `firebaseReducer` is made up of multiple "slice reducers"
-([outlined in reducers docs](/docs/recipes/reducers.md)) combined using
-[`combineReducers`](https://redux.js.org/docs/api/combineReducers.html)
-following the patterns outlined in
-[the redux docs](https://redux.js.org/docs/recipes/StructuringReducers.html).
