title: Angular expression to check if model is array or object
body: <p>How can I check if an angular model is an array or an object? Is there a built in or do I have to write a filter <code>isArray</code> with <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/isArray" rel="nofollow"><code>Array.isArray()</code></a></p>
  
  <p><a href="http://docs.angularjs.org/api/ng/function/angular.isArray" rel="nofollow"><code>{{[] | isArray}}</code></a>  doesn't work</p>
