Hey folks, maybe you can help:
Not passing tests for if the prop is missing or undefined.
Not popping value on properly.
I don’t think the delete works.
Here’re the results of the tests:
Passed
After `updateRecords(recordCollection, 5439, "artist", "ABBA")` , `artist` should be the string `ABBA`
Failed
After `updateRecords(recordCollection, 5439, "tracks", "Take a Chance on Me")` , `tracks` should have the string `Take a Chance on Me` as the last element.
Failed
After `updateRecords(recordCollection, 2548, "artist", "")` , `artist` should not be set
Passed
After `updateRecords(recordCollection, 1245, "tracks", "Addicted to Love")` , `tracks` should have the string `Addicted to Love` as the last element.
Passed
After `updateRecords(recordCollection, 2468, "tracks", "Free")` , `tracks` should have the string `1999` as the first element.
Failed
After `updateRecords(recordCollection, 2548, "tracks", "")` , `tracks` should not be set
Passed
After `updateRecords(recordCollection, 1245, "albumTitle", "Riptide")` , `albumTitle` should be the string `Riptide`
Here’s my code:
// Setup
var 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 !== undefined) {
records[id][prop] = value;
} else if (prop === 'tracks' && records[id][prop] === undefined) {
records[id][prop] = value;
} else if (prop === 'tracks' && records[id].hasOwnProperty(prop)) {
records[id][prop].push(value);
} else if (value === '') {
delete records[id][prop];
}
return records;
}
