AngularJS ng-repeat, comma separated with ‘and’ before the last item

Question

$last is the truthy value.. so it holds either true or false and it doesn’t hold the last element index..

I guess below expression should solve your problem

<p><span ng-repeat="user in Users">
            {{user.Username}} {{$last ? '' : ($index==Users.length-2) ? ' and ' : ', '}}
  </span></p>

Also make sure that you have the expression with $last within ng-repeat element and not outside of it
