A simple merge utility

Here is: I tried quite a few different ways and I keep getting bummer!

index.js 
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 :)";
utilities.js 
function merge(content, values) {
    content = content.replace("%first_name%", values[%first_name%]);
  return content;
}


module.exports.merge = merge;

function merge(content, values) {

  for (var key in values){

    content = content.replace("%" + key + "%", values[key]);

  }

  return content;
}


module.exports.merge = merge;

You were treating variables as string. Make sure you treat them as variables to pass data.
