title: JSON keys with dollar sign
body: <p>I am trying to parse some json using <code>js</code> and <code>angularjs</code>, which it's path is: <code>item["sub:item"].$.url</code>.</p>
  
  <p>Everything goes fine, until the <code>$</code> sign. I have tried to do ng-repeat with on <code>item["sub:item"].["$"].url</code> and <code>item["sub:item"].$.url</code> but nothing works.</p>
