Hi Campers, thanks in Advance for your help.
I don´t understand the use of these brackets alongside, [id] and [prop], in:
{records[id][prop] = value;}
Apparently that would assign a “value” to a “property” nested in a specific “Id”, am I right?
If it was nested, I expected it to be:
{recordCollection.id[“prop”]}
as in a previous exercise:
ourStorage.cabinet[“top drawer”].folder2;
My code:
// Setup
const recordCollection = {
2548: {
albumTitle: 'Slippery When Wet',
artist: 'Bon Jovi',
tracks: ['Let It Rock', 'You Give Love a Bad Name']
},
2468: {
albumTitle: '1999',
artist: 'Prince',
tracks: ['1999', 'Little Red Corvette']
},
1245: {
artist: 'Robert Palmer',
tracks: []
},
5439: {
albumTitle: 'ABBA Gold'
}
};
// Only change code below this line
function updateRecords(records, id, prop, value) {
if (prop !== "tracks" && value !== "")
{records[id][prop] = value;}
else if (prop === "tracks" &&
records[id].hasOwnProperty("tracks") === false)
{records[id][prop] = [value];}
else if (prop === "tracks" && value !== "")
{records[id][prop].push(value);}
else if (value === "")
{delete records[id][prop];}
return records;}
updateRecords(recordCollection, 5439, "artist", "ABBA");
updateRecords(recordCollection, 5439, "tracks", "Take a Chance on Me");
updateRecords(recordCollection, 2548, "artist", "");
updateRecords(recordCollection, 1245, "tracks", "Addicted to Love");
updateRecords(recordCollection, 2468, "tracks", "Free");
updateRecords(recordCollection, 2548, "tracks", "");
updateRecords(recordCollection, 1245, "albumTitle", "Riptide");
