How to use multiple parameters in a handlebar helper with meteor?

Question

Your logic is good, just make some changes to the template

<template name="myTemplate">
  {{testHelper "value1" "value2"}}
</template>

Bare in mind that the testHelper function is only defined in the myTemplate template.

If you want to register testHelper globally you’ll need to do something like this

Handlebars.registerHelper('testHelper', function(foo, bar){
  console.log(foo);
  console.log(bar);
});
