title: Can you go backwards through react-router v4 hashHistory?
body: <p>Wondering how to go back to a previous route in a react web app using hashRouter instead of browserRouter in react-router v4?</p>
  
  <p>I've found <a href="https://stackoverflow.com/questions/30915173/react-router-go-back-a-page-how-do-you-configure-history">this</a> question which doesn't seem to work even though it says no browser mixin needed (plus I think its talking about an older react-router version) however, every other solution I've seen depends on browserHistory.</p>
  
  <p>Is it possible with hashHistory?</p>
