Record collection lesspm

// Setup
var collection = {
“2548”: {
“album”: “Slippery When Wet”,
“artist”: “Bon Jovi”,
“tracks”: [
“Let It Rock”,
“You Give Love a Bad Name”
]
},
“2468”: {
“album”: “1999”,
“artist”: “Prince”,
“tracks”: [
“1999”,
“Little Red Corvette”
]
},
“1245”: {
“artist”: “Robert Palmer”,
“tracks”: [ ]
},
“5439”: {
“album”: “ABBA Gold”
}
};
// Keep a copy of the collection for tests
var collectionCopy = JSON.parse(JSON.stringify(collection));

// Only change code below this line
function updateRecords(id, prop, value) {
if(prop!=“tracks”&&value!=="")
{
id[prop]=value;
}
if (prop==“tracks”&& !id.hasOwnedProperty(prop))
{
value = [];
“tracks”.unshift(value);
}
if(prop==“tracks”&&value!=="")
{
“tracks”.push(value);
}
if(value==="")
{
delete id[prop];
}

return collection;
}

// Alter values below to test your code
updateRecords(5439, “artist”, “ABBA”);

I’m not sure why this doesn’t work?

Use bracket notation on collection like collection[id][prop]. You don’t work with collection

OK. I just filtred no replies.
