How do i get select multiple values or checkbox multiple selections using mustachejs?

[CodeCurosity]

I can get single values just fine but i am not sure how to get multiple selected values using select or checkbox control.

var formdata = jQuery("#myform").serializeArray();
  var data = {};
  jQuery(myform).each(function(index, obj){
      data[obj.name] = obj.value;
  });
  var rendered = Mustache.render(template, data);

Thank you.
