Doesn't hurt to also check and make sure it is a string and if not return nothing.

Handlebars.registerHelper('lowercase', function (str) {
  if(str && typeof str === "string") {
    return str.toLowerCase();
  }
  return '';
});

Usage :

// now let's pass a string or variable to our helper
{{lowercase 'MY NAME IS'}}

Output :

my name is
