Tell us what’s happening:
I just do not understand this exercise.
I can’t get it right without looking at hint or watching videos and even with the videos online, i still do not really get how to solve this.
Can someone maybe explain it to me? Maybe from a different angle than videos on online? My code is below.
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 !== "") {
collection[id][prop]=(value);
}
else if (prop === "tracks" && "tracks" == "") {
collection[id][prop].push[value];
}
else if (prop === "tracks" && value !== "") {
collection[id][prop].push(value);
}
else if (value == "") {
delete collection[id][prop];
}
}
// Alter values below to test your code
updateRecords(5439, "artist", "ABBA");
