title: angularjs difference between $eval and dot access
body: <ol>
  <li><code>$scope.$parent.$parent.GoodsVal.GoodsItem.MinOrderUnit</code></li>
  <li><code>$scope.$eval('$parent.$parent.GoodsVal.GoodsItem.MinOrderUnit')</code></li>
  </ol>
  
  <p>What is different 1 and 2?</p>
  
  <p>I think 1 is better.</p>
