I'm trying to solve this challenge, but no matter what I do I always get it wrong!!

I simply cannot see what I'm doing wrong!! This works perfectly on another project I'm doing

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

var mailValues = {
first_name: ""
};

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 :)";
utilities.js
function merge(content, values) {
  for (var key in values)
  {
   content = content.replace("%first_name%", values[key]);
  }

  return content;
}


module.exports.merge = merge;

You're really close, here's a couple of hints:

  • don't modify index.js, your changes only go in utilities.js in the merge function
  • your merge routine should replace any and all keys, not just "first_name"

I'm betting you can get it now without an explicit spoiler.
