Basic: Record Collection

Tell us what’s happening:

I am struggling to figure out why I am still getting this error:

" After updateRecords(5439, "tracks", "Take a Chance on Me") , tracks should have "Take a Chance on Me" as the last element."

the other check list items have come back with a tick, however, this one remains.

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"
}
};

// Only change code below this line
function updateRecords(id, prop, value) {

if (prop !== "tracks" && value !== "") {
  collection[id][prop] = value;
}

else if (prop === "tracks" && collection[id][prop] === undefined) {
  collection[id][prop] = [];
  collection[id][prop] = value;
}

else if (prop === "tracks" && value !== "") {
  collection[id][prop].push(value);
}

else if (value === "") {
  delete collection[id][prop];
}

return collection;
}

updateRecords(5439, "artist", "ABBA");

Challenge: Record Collection

Link to the challenge:

Have a look

collection[id][prop] = [];
  collection[id][prop] = value;

Since you have made collection[id][prop] an array.
You have to push the value onto it
