Tell us what’s happening:
If I put space between the quotes like this , value === ’ ’ , it throws error. Does putting space in quotes make it non empty string? Or is it something else that is causing the error?
else if(value === ‘’){
delete object[id][prop];
}
Your code so far
// Setup
var collection = {
2548: {
albumTitle: 'Slippery When Wet',

},
2468: {
albumTitle: '1999',

},
1245: {
artist: 'Robert Palmer',
tracks: []
},
5439: {
albumTitle: 'ABBA Gold'
}
};
// Only change code below this line
function updateRecords(object, id, prop, value) {
if(prop !== 'tracks' && value !== ''){
object[id][prop] = value;
}
else if(prop === 'tracks' && !object[id].hasOwnProperty('tracks')){
object[id]['tracks'] = [value]
}
else if(prop === 'tracks' && value !== ''){
object[id]['tracks'].push(value);
}
else if(value === ''){
delete object[id][prop];
}
return object;
}
updateRecords(collection, 2548, 'artist', '');
console.log(collection[2548]);
