title: Angular2 Browser History Navigation
body: <p>How to navigate to previous state and back in the browser history.</p>
  
  <p>I remember AngularJS supported this:</p>
  
  <pre><code>$window.history.back();
  </code></pre>
  
  <p>React supports this:</p>
  
  <pre><code>import { browserHistory } from 'react-router'
  browserHistory.goBack();
  </code></pre>
  
  <p>How to back and previous browser history in Angular 2 >= v2.1.0</p>
