Tell us what’s happening:
Hello everyone,
I am having trouble solving the exercise “Record Collection”,
please see my code so far and suggest me corrections/ improvements
without telling me the solution!
thank you so much for your help!
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": [ //if prop is "tracks" and value isn't empty (""), push the value onto the end of the album's existing tracks array.
"1999",
"Little Red Corvette"
]
},
"1245": {
"artist": "Robert Palmer",
"tracks": [ ] //If value is empty (""), delete the given property from the album.
},
"5439": {
"album": "ABBA Gold"
// no tracks prop: create an empty array before adding the new value to the album's corresponding property.
}
};
// 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) {
var id = collection[""]; //var id will receive the id parameter to look for in collection object
for (var id in collection) {
if (value !== "") { // if prop/key does not exist(empty string)
collection.id.prop[value]; //set its value
}
else if (prop == "tracks" && value !== ""){ //If the prop parameter is equal to "tracks" //and the value isn’t an empty string, push the value onto the end of the tracks array.
collection.id.prop.push[value];
}
else if (value == "" ) {
delete collection.id.prop[""]; // if value is empty delete its prop
}
else {
return collection;
}
}
}
// Alter values below to test your code
updateRecords(5439, "artist", "John");
