Redux Combine Reducers

Combine reducers is a powerful tool that allows you to separate concerns when it comes to managing state within Redux. Once an application grows to be large enough that using one single reducer for all stateful logic no longer seems feasible or is getting out of hand this functionality should be used. You can break up the logic in to multiple reducers that will each be able to watch for seperate events or even be able to watch for the same event being fired and do different actions.
