I manage to solve this problem within 30 minutes but I am not sure if this is actually how it is done. I know I already solved the problem but I am just curios if my approach is somewhat ok and I just want to contribute in the Forum as well maybe.(have something posted in the forum)
Your code so far
// Setup
var collection = {
2548: {
albumTitle: 'Slippery When Wet',
artist: 'Bon Jovi',
tracks: ['Let It Rock', 'You Give Love a Bad Name']
},
2468: {
albumTitle: '1999',
artist: 'Prince',
tracks: ['1999', 'Little Red Corvette']
},
1245: {
artist: 'Robert Palmer',
tracks: []
},
5439: {
albumTitle: 'ABBA Gold'
}
};
// Only change code below this line
function updateRecords(object, id, prop, value) {
if(prop != "tracks" && value != ""){
object[id][prop] = value;
}
if(prop == "tracks" && object[id].hasOwnProperty(prop) == false){
object[id][prop] = [value];
}
if(prop == "tracks" && value){
object[id][prop].push(value);
}
if(value == ""){
delete object[id][prop];
}
return object;
}
console.log(updateRecords(collection, 2468, 'tracks', 'Take a Chance on Me'));
