Mongoose Built-in validation

One of the core concepts of Mongoose is that it enforces a schema on top of a schema-less design such as MongoDB. In doing so, we gain a number of new features, including built-in validation. By default, every schema type has a built-in required validator available. Furthermore, numbers have both min and max validators and strings have enumeration and matching validators.
