How to remove the last comma when using for loop?

Take the comma off the end of the string. Then add a check to see if i is less than the collection length - 1. Something like…

Nationalitiesstr = Nationalitiesstr + this.nationalityData.find(x => x.libraryID == Nationalities[i].nationalityXid).libraryName;

if (i < Nationalities.length -1)
  Nationalitiesstr += “, “; 

The String.Join Method … may also work.

    {% with product_in_series.product as product %}
    {%if not forloop.first%}
        "<img src='{% version product.get_overview 'page_image' %}'>"
        {%if not forloop.last%},{%endif%}
    {%endif%}
    {% endwith %}
{%endspaceless%}{% endfor %}
