Your code so far

        var findEditThenSave = (personId, done)=>{
  var foodToAdd = 'hamburger';
  Person.findById(personId, (err, persondata)=>{
    if (err) return console.log(err);
//     lets add hamburg to the array of foods
    persondata.favoriteFoods.push(foodToAdd);
//     lets save what we have added
    persondata.save((err, personUpdate)=>{
      if(err) return console.log(err);
       done(null, personUpdate);
    });
     
  });

};

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
