// #25 - LOGS

/* EJERCICIO:
3+
* Explora el concepto de "logging" en tu lenguaje. Configúralo y muestra
4+
* un ejemplo con cada nivel de "severidad" disponible.
5+
*
6+
* DIFICULTAD EXTRA (opcional):
7+
* Crea un programa ficticio de gestión de tareas que permita añadir, eliminar
8+
* y listar dichas tareas.
9+
* - Añadir: recibe nombre y descripción.
10+
* - Eliminar: por nombre de la tarea.
11+
* Implementa diferentes mensajes de log que muestren información según la
12+
* tarea ejecutada (a tu elección).
13+
* Utiliza el log para visualizar el tiempo de ejecución de cada tarea. */

/*Info Note:
160+
Continuous Integration is a development practice where developers frequently integrate their code changes into a shared repository, usually several times a day.
161+
Each integration is automatically tested to detect errors quickly. This helps ensure that the codebase remains stable and that new changes do not break existing functionality.
162+
Tools commonly used for CI include Jenkins, Travis CI, CircleCI, GitHub Actions, and GitLab CI.
163+
CD (Continuous Delivery or Continuous Deployment):
164+
165+
Continuous Delivery is an extension of CI that ensures that the code is always in a deployable state. This means that after passing automated tests, the code can be deployed to production at any time.
166+
Continuous Deployment takes it a step further by automatically deploying every change that passes the tests to production without manual intervention.
167+
This practice allows for faster release cycles and more frequent updates to the application. */
