Mongo Basics Drills

1. Get all:
  db.restaurants.find();

2. Limit and sort:
  db.restaurants.find({}).sort({name: 1}).limit(10);
 
3. Get by _id:
  const searchId = db.restaurants.findOne({}, {_id: 1})._id;
  db.restaurants.findOne({_id: searchId});

4. Get by value:
  db.restaurants.find({borough: "Queens"});
  
5. Count:
  db.restaurants.count();
  
6. Count by nested value:
  db.restaurants.count({"address.zipcode": "11206"});

7. Delete by id:
  const deleteId = db.restaurants.findOne({}, {_id: 1})._id;
  db.restaurants.remove({_id: deleteId});

8. Update a single document:
  const updateId = db.restaurants.findOne({}, {_id: 1})._id;
  db.restaurants.updateOne({_id: updateId}, {$set: {name: "Bizz Bar Bang"});
  
9. Update many documents:
  db.restaurants.updateOne({"address.zipcode": "10035"}, {$set: {"address.zipcode": "10036"}});
