title: Can someone give me an example of using time travel debugging on vuex?
body: <p>I did google <strong>vuex</strong> <strong>time-travel debugging</strong>, e.g. <a href="https://alligator.io/vuejs/vue-devtools/" rel="nofollow noreferrer">Using the Vue.js Devtools</a></p>
  
  <p>I also tried it myself on <a href="http://todomvc.com/" rel="nofollow noreferrer">TodoMVC</a>, so I get the basic idea of it, like roll back to the previous state. </p>
  
  <p>But I still don't see how it would help me debug my code. So can someone give a specific example of using it to catch a bug?</p>
