Your code so far

        var queryChain = function(done) {
  var foodToSearch = "burrito";
 const query = Person.find({favoriteFoods:foodToSearch})
 .select({age: 0})
 .exec((err, people)=>{
   if(err) return console.log(err)
   done(null, people)

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.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

Hope that helps
