Esto es muy útil cuando necesitas:

* Tener lógica compartida (la misma lógica de código una y otra vez).
* Compartir conexiones a bases de datos.
* Imponer seguridad, autenticación, requisitos de roles, etc.
* Y muchas otras cosas...

Todo esto, mientras minimizas la repetición de código.

## Primeros Pasos

Veamos un ejemplo muy simple. Será tan simple que no es muy útil, por ahora.
