Implementation of the merge method

Hi Team, I run this function in Visual Code and replace the name in the content, but the Challenge does not approve it. I don't know what is missing!!!! Greetings...

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;

This implementation will only replace a token for "first name". What the instructions are asking for is a module that would replace any number of tokens using an object with any number of values.

Hint: You'll probably need a loop.

The video on Binding Values gives an example of how to do this. In the video, he says "You will want to Cycle over the keys, then Replace all {{key}} with the value from the values object." The only difference is that you aren't using the double curly braces as the key delimiter, but rather percent signs. If you take the rest of the info from the code in the video, it should work for you (that's what I did and it worked).
