for kind of scenario, create helper.

here implementation

handlebars.registerhelper('commalist', function(items, options) {   var out = '';    for(var i=0, l=items.length; i<l; i++) {     out = out + options.fn(items[i]) + (i!==(l-1) ? ",":"");   }   return out; }); 

and template

<div>    <div>     {{#commalist this}}        <span>{{alert_description}}</span>     {{/commalist}}    </div> </div> 

in fact, helper here comma. can still put html inside helper (span, div, ...)
