Tell us what’s happening:
Hello, i have a question, why if i put:
collection[id][prop] instead of collection[id][“tracks”] it dosen’t work?
Is this a bug or what? I really don’t get it why it dosen’t work
If you have better idea how to write this code cleaner (i am new and i want to get good practice)
Thank you world!
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));
[spoiler]// Only change code below this line
function updateRecords(id, prop, value) {
if(value == ""){
delete collection[id][prop];
}
else if(prop != "tracks" && value != ""){
collection[id][prop] = value;
}
else if(prop = "tracks" && value != "" && !collection[id]["tracks"]){
collection[id]["tracks"] = [];
collection[id]["tracks"].push(value);
}
else if(prop = "tracks" && value != "" && collection[id]["tracks"]){
collection[id]["tracks"].push(value);
}
return collection;
}[/spoiler]
// Alter values below to test your code
updateRecords(5439, "tracks", "Take a Chance on Me")
