title: Is store.dispatch in Redux synchronous or asynchronous
body: <p>I realize this is a basic question but I had no luck finding the answer elsewhere.</p>
  
  <p>Is <code>store.dispatch</code> synchronous or asynchronous in <code>Redux</code> ?</p>
  
  <p>In case it is asynchronous is there a possibility to add a callback after the action has been propagated as it is possible with <code>React</code> ?</p>
