Value change on drop down or check box

JavaScript
42

I have retained the first lot of code completely.

and commented some lines in 2nd lot

 var prices = [59, 236, 1475];
  var form = document.querySelector("#order");
  var select = form.elements.license_type;
  var checkboxes = getCheckboxes(form);
  // var submit = form.elements.submit;
  select.addEventListener("change", updatePriceHandler);
  checkboxes.forEach(function addCheckboxHandler(checkbox) {
    checkbox.addEventListener("click", updateTotalHandler);
  });
  // submit.classList.add("hide");
  // addBuyNow(submit);
