So what you want to do is create a for loop which will pluck out all of the placeholders and replace their contents with their associated value. for example %first_name% with Janet.

This can be achieved as per below:

function merge(content, values) {
  for (placeholder in values) {
    content = content.replace("%"+placeholder+"%", values[placeholder]);
  }
  return content;
}

module.exports.merge = merge;
