Tell us what’s happening:
Hi,
I’m having somme difficulties with some “if” conditions in this exercices. Also I’m not sure how I should create an empty arry and update it accordingly.
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!= "") {
// push the value onto the end of the album's existing tracks array.
collection[id].push(value);
}
if (prop != "tracks" & value !="") {
// update or set the value for that record album's property.
collection[id].push(prop[value]);
}
if (prop="tracks" & collection.tracks=null) {
//create an empty array before adding the new value to the album's corresponding property.
// I DON'T KNOW HOW TO DO!
}
if (value="") {
// delete the given prop property from the album.
collection[id].prop="";
}
return collection;
}
// Alter values below to test your code
updateRecords(5439, "artist", "ABBA");
