In Mustache templating is there an elegant way of expressing a comma separated list without the trailing comma?

Question

I am using the Mustache templating library and trying to generate a comma separated list without a trailing comma, e.g.

red, green, blue

Answer 1

In case using Handlebars is an option, which extends the capabilities of Mustache, you could use a @data variable:

{{#if @last}}, {{/if}}
