Answer given by  mpm is not working it gives the error     Duplicates in a repeater are not allowed  Use  track by  expression to   specify unique keys  Repeater   0   Duplicate key   1    To avoid this along with      ng-repeat  t in getTimes 4     use      track by  index   like this      LT div ng-repeat  t in getTimes 4  track by    index  GT TEXT LT  div GT

All answers here seem to assume that items is an array  However  in AngularJS  it might as well be an object  In that case  neither filtering with limitTo nor array slice will work  As one possible solution  you can convert your object to an array  if you don t mind losing the object keys  Here is an example of a filter to do just that   myFilter filter  obj2arr   function         return function obj            if  typeof obj      object                 var arr       i   0  key              for  key in obj                     arr i    obj key                   i                              return arr                    else               return obj                          Once it is an array  use slice or limitTo  as stated in other answers
