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

For JSON data I suggest:

Mustache.render(template, settings).replace(/,(?=\s*[}\]])/mig,'');

The regexp will remove any , left hanging after the last properties.

This will also remove , from string values contining ", }" or ", ]" so make sure you know what data will be put into your JSON
