Tell us what’s happening:
I’m confused as to why FCC is requiring the parameter value to be in brackets in the second level of the IF statement but not in the first level?
When I run the updateRecords function without using brackets in either levels of the IF statement through a Google Chrome snippet, it works fine.
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 {
delete collection[id][prop];
}
return collection;
}
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 {
delete collection[id][prop];
}
return collection;
}
// Alter values below to test your code
updateRecords(5439, "artist", "ABBA");
updateRecords(5439, "tracks", "Take a Chance on Me");
updateRecords(2548, "artist", "");
updateRecords(1245, "tracks", "Addicted to Love");
updateRecords(2468, "tracks", "Free");
updateRecords(2548, "tracks", "");
updateRecords(1245, "album", "Riptide")
