How to delete array element in document and save with Mongoose?

To delete array element in document and save with Mongoose, we can use the updateOne method with the $pullAll operator.

For instance, we write

Favorite.updateOne({
  name
}, {
  $pullAll: {
    favorites: req.params.deleteUid,
  },
});

to call updateOne with an object to search for the document with the name value set to name.

The 2nd object has the $pullAll property which lets us remove the favorites entries in the selected Favorite document with the _id set to req.params.deleteUid.
