| Otra solución diferente podría ser agregar una propiedad como `message.isRead = true` a un mensaje después de leerlo. Como los objetos de mensajes son administrados por otro código, generalmente se desaconseja, pero podemos usar una propiedad simbólica para evitar conflictos. | ||

| En la tarea anterior solo necesitábamos almacenar el hecho de "sí / no". Ahora necesitamos almacenar la fecha, y solo debe permanecer en la memoria hasta que el mensaje sea recolectado como basura. | ||
|
|
||

la clase incorporada (builtin) se llama Date: OJO

| Por lo general, las propiedades de un objeto o elementos de un array u otra estructura de datos se consideran accesibles y se mantienen en la memoria mientras esa estructura de datos permanezca en la memoria. | ||
|
|
||
| Por ejemplo, si colocamos un objeto en un array, mientras el array esté vivo, el objeto también estará vivo, incluso si no hay otras referencias a él. |
