title: How to push data into more objects with the same properties
body: <p>I try to learn angularjs. I have this array with objects:</p>
  
  <pre><code>ctrl.list = [
    {
      name: 'Superman',
      location: ''
    },
    {
      name: 'Batman',
      location: 'Wayne Manor'
    }
  ];
  </code></pre>
  
  <p>And I want to add more heros inside, but I don't know how.
  I was thinking of this way:</p>
  
  <pre><code>ctrl.addHero = function(prop, value) {
    ctrl.list.push({prop: value});
  };
  </code></pre>
  
  <p>But in this way I add only one prop each time.</p>
