<span ng-repeat="tag in tags">
   {{tag + "," }}
</span>

I need to remove , after the last element. I know ng-if="$last" can solve the problem. But, as I don't have any parent element for {{tag}} I can't use ng-if so, just need some work around.

You should use a ternary together with () in order to prevent weird outcome:

<span ng-repeat="tag in tags">
   {{tag + ($last ? "" : ",")}}
</span>

Use a ternary operator within the mustache like this:

<span ng-repeat="tag in tags">
   {{tag + $last ? "" : "," }}
</span>

Cheers!
