  //
});

Note:

• mongoose's doc.validate evaluates schemaType.validate in reverse order
  • In the previous example, isLength has been evaluated first
• Can not validate a field if value is empty and schemaType.required is false
  • It is also a specification of mongoose
• Ref
  • mongoose schemaType.validate
