Se te da un objeto literal que representa una parte de tu colección de álbumes musicales. Cada álbum tiene un número de id único como clave y varias otras propiedades. No todos los álbumes tienen una información completa.
|
||||
You are creating a function that aids in the maintenance of a musical album collection. The collection is organized as an object that contains multiple albums which are also objects. Each album is represented in the collection with a unique `id` as the property name. Within each album object, there are various properties describing information about the album. Not all albums have complete information.
|
||||
|
||||
Empiezas con una función `updateRecords` la cual toma un objeto literal, `records`, que contiene el álbum musical de la colección, un `id`, `prop` (como `artist` o `tracks`), y `value`. Completa la función usando las reglas siguientes para modificar el objeto pasado a la función.
|
||||
The `updateRecords` function takes 4 arguments represented by the following function parameters:
|
||||
|
||||
- Tu función siempre debe devolver el objeto de colección de registros completo.
|
||||
- Si `prop` no es `tracks` y `value` no es una cadena vacía, actualiza o establece la propiedad `prop` del album a `value`.
|
||||
- Si `prop` es `tracks` pero el álbum no tiene una propiedad `tracks`, crea un arreglo vacío y agrégale `value` a él.
|
||||
- Si `prop` es `tracks` y `value` no es una cadena vacía, agrega `value` al final del arreglo de `tracks` existentes del álbum.
|
||||
- Si `value` es una cadena vacía, elimina esa propiedad `prop` del álbum.
|
||||
- `records` - an object containing several individual albums
|
||||
- `id` - a number representing a specific album in the `records` object
|
||||
- `prop` - a string representing the name of the album’s property to update
|
||||
- `value` - a string containing the information used to update the album’s property
|
||||
|
||||
**Nota:** Se usa una copia del objeto `recordCollection` para las pruebas.
|
||||
Complete the function using the rules below to modify the object passed to the function.
|
||||
|
||||
- Your function must always return the entire `records` object.
|
||||
- If `value` is an empty string, delete the given `prop` property from the album.
|
||||
- If `prop` isn’t `"tracks"` and `value` isn't an empty string, assign the `value` to that album’s `prop`.
|
||||
- If `prop` is `"tracks"` and `value` isn’t an empty string, add the `value` to the end of the album’s existing `"tracks"` array.
|
||||
- If the album doesn’t have a `"tracks"` property, create a new array for the album's `"tracks"` property before adding the `value` to it.
|
||||
|
||||
**Note:** A copy of the `recordCollection` object is used for the tests. You should not directly modify the `recordCollection` object.
