Slice By Index With Increment

I have something like this:

{{$index+1}} - {{atma.weapon}}

Solution 1:

1st:

<div ng-repeat="atma in data">
   <ul ng-if="$index % 3 == 0">
       <li><span>{{data[$index]}} </span>
       </li>
       <li ng-if="$index+ 1 < data.length"><span>{{data[$index+1]}} </span>
       </li>
       <li ng-if="$index+ 2 < data.length"><span>{{data[$index+2]}} </span>
       </li>
   </ul>
</div>

2nd:

<div ng-repeat="atma in data">
   <ul ng-if="$index % 3 == 0" ng-init="tmp = data.slice($index, $index + 3)">
       <li ng-repeat="atma1 in tmp"><span>{{atma1}}</span>
       </li>
   </ul>
</div>
