Is it possible to utilize ng-repeat and !$last in order to list answers separated by commas without displaying the last comma? Below is the current HTML code that I have been working with:
<h3 ng-repeat="answer in correctAnswers" ng-show="!$last">
{{answer + "," + " " }}
</h3>
Instead of using a separate span and toggling visibility, I suggest sticking closer to your original attempt:
<h3 ng-repeat="answer in correctAnswers">
{{answer + ($last ? '' : ',')}}
</h3>
Keep it simple with boolean logic and string concatenation, no need for extra directives
If you're looking for an easy solution, give this a shot
<h3 ng-repeat="solution in correctSolutions">
{{solution}}<span ng-show="!$last"> + "," + " "<span>
</h3>
