title: Exclamation mark after hash (#!) in angularjs app
body: <p>I have just noticed that I have an exclamation mark after a hash (#!) in all of my routes. I'm not sure how and why I got them because earlier today I didn't have them. </p>
  
  <p>If there is any solution to get rid of them, I would appreciate if someone can explain me what is it( and how I came to have them). </p>
  
  <p>So, the only solution that I have found so far is to put manually put the exclamation mark on every href in my app, but this annoys me and I have no idea what to do. </p>
  
  <p>I generated my app with yeoman generator and my app.js looks like this: </p>
  
  <pre><code>angular
    .module('appNameApp', [
      'ngAnimate',
      'ngCookies',
      'ngResource',
      'ngRoute',
      'ngSanitize',
      'ngTouch'
    ])
    .config(function ($routeProvider) {
      $routeProvider
        .when('/', {
          templateUrl: 'views/main.html',
          controller: 'MainCtrl',
          controllerAs: 'main'
        })
        .when('/about', {
          templateUrl: 'views/about.html',
          controller: 'AboutCtrl',
          controllerAs: 'about'
        })
        .when('/jaspo', {
          templateUrl: 'views/about.html',
          controller: 'jaspoCtrl',
          controllerAs: 'vm'
        })
        .otherwise({
          redirectTo: '/'
        });
    });
  </code></pre>
