title: Syntax Error: Token '&&' not a primary expression
body: <p>I hae the following code in my ionic app view :  </p>
  
  <pre><code>&lt;ion-item 
      ng-repeat="milestone in project.milestones" 
      href="#/tab/activity/{{milestone.slug}}/milestone" 
      ng-style="{{now | amDifference : null : 'days'}} &gt; {{milestone.due_date | amDifference : null : 'days'}} &amp;&amp; {'color':'red'} || {'color': 'blue'}"&gt;
  </code></pre>
  
  <p>However it is giving me this error:</p>
  
  <blockquote>
    <p>Error: [$parse:syntax] Syntax Error: Token '&amp;&amp;' not a primary expression at column 6 of the expression [0 >  &amp;&amp; {'color':'red'} || {'color': 'blue'}] starting at [&amp;&amp; {'color':'red'} || {'color': 'blue'}].</p>
  </blockquote>
  
  <p>Hovever the above error doesnt seem to affect execution (for now i think) i have no idea where it is comming from.
  in the code above i am trying to compare the current time to a set time using moment.js</p>
