title: How to trigger off callback after updating state in Redux?
body: <p>In React, state is not be updated instantly, so we can use callback in <code>setState(state, callback)</code>. But how to do it in Redux?</p>
  
  <p>After calling the <code>this.props.dispatch(updateState(key, value))</code>, I need to do something with the updated state immediately.</p>
  
  <p>Is there any way I can call a callback with the latest state like what I do in React?</p>
