Tell us what’s happening:

the command kept saying I need to have tracks array as a string. please help

Your code so far

// 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(value === “”){
delete records[id][prop]
}else if(prop !== “tracks” && value !== “”){
records[id][prop] = value
}else if(prop === tracks && value !== “”){
if(records[id].hasOwnProperty(“tracks”) === false ){
records[id][prop] = ;
}
records[id][prop].push(value);
}

return records;
}

updateRecords(recordCollection, 5439, ‘artist’, ‘ABBA’);

// The problem is down below, i think the “tracks” prop still not defined
// Because the last else If just add an empty array , not with “tracks” prop
// HELP ㅠㅠ
updateRecords(recordCollection, 5439, “tracks”, “Take a Chance on Me”)

Hello and welcome !

Here:

Since prop is supposed to be a string, you should add quotes (“”) around tracks ("tracks"). You probably just forgot tho, cause you did it on the first else if line.

Happy coding !
