Backend trouble...

I am not understanding anything about this backend stuff. Can I just get an answer to this question please.

var utilities = require("./utilities");

var mailValues = {};

mailValues.first_name = "Janet";

var emailTemplate = "Hi %first_name%! Thanks for completing this code challenge :)";

var mergedContent = utilities.merge(emailTemplate, mailValues);

//mergedContent === "Hi Janet! Thanks for completing this code challenge :)";
function merge(content, values) {
  for(var key in values) {
     content = content.replace("{{" + key + "}}", values[key]);
  return content;

module.exports.merge = merge;

You're pretty close, but you may have misread the instructions. They say that "You should be able to pass in a string with placeholders with percent signs (%) surrounding them."

But your replacement code is looking for placeholders with double braces ({{ }}) surrounding them instead.
