Tell us what’s happening:
Everything works except I am not able to delete the collection property.
Frequently getting error message - updateRecords(2548,“tracks”,""); and updateRecords(2548,“artist”,"");
I am unable to delete both properties, though my code is correct. I tested it separately on my computer. It works … but challenge is not showing success… someone help please…
Your code so far
// 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 != "" )
{
if(collection[id][prop])
{
collection[id][prop].push(value);
}else {
collection[id][prop] = [value];
}
}else if (value !== " ")
{
collection[id][prop] = value;
}else if(value == " ")
{
delete collection[id].prop;
}
return collection;
}
// Alter values below to test your code
updateRecords(5439, "artist", "ABBA");
updateRecords(5439,"tracks","Take a Chance a Me");
updateRecords(2548,"artist","");
updateRecords(1245,"tracks","Addicted to Love");
updateRecords(2468,"tracks","Free");
updateRecords(2548,"tracks","");
updateRecords(1245,"album","Riptide");
