Using comma as list separator with AngularJS
Solution 1:
You could do it this way:
<b ng-repeat="email in friend.email">{{email}}{{$last ? '' : ', '}}</b>
..But I like Philipp's answer :-)
Solution 2:
Just use Javascript's built-in join(separator) function for arrays:
<li ng-repeat="friend in friends">
<b>{{friend.email.join(', ')}}</b>...
</li>
