Your code so far
// Setup
var collection = {

"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) {

}
else if (value===""){

return collection;
}
// Alter values below to test your code
updateRecords(5439, "artist", "ABBA");
Hello. Only 1 test doesnt complete with current code. im guessing its because of the push condition.
More importantly, can someone tell me, in the instructions, whenever " value is or isnt empty("") " is mentioned, does it refer to the “value” argument of the function or does it sometimes refer to the value of the property of the object selected by functions “prop” argument ?
The following line is confusing me:
Either im misunderstanding it, or it should refer to the property value inside the object…
