const removeManyPeople = (done) => {
  const nameToRemove = "Mary";
  Person.remove({name: nameToRemove}, (err, response) => {
    if(err) return console.log(err);
    done(null, response);
  })
};

Code Explanation

• remove() sends a remove command to MongoDB to remove all matched documents. In this case, all documents with a name of Mary are removed.
• The response is a JSON object containing properties such as deletedCount - containing the number of documents removed from the collection.
