Use User.create({ name, email }) or create a new instance and save: const user = new User(data); await user.save(). Both create a new document. User.create is a convenience that does both in one step.
User.find() returns all, User.findOne({ email }) returns one by query, User.findById(id) returns one by id. Use query operators like $gt, $lt, $in, $and, $or for filtering: User.find({ age: { $gt: 18 } }).
Use skip and limit: User.find().skip(page * pageSize).limit(pageSize). For large datasets, use cursor-based pagination with the id for better performance, since skip slows down on large offsets.
