Build A Record Collection

JavaScript

The third test is failing even though when I run it in the FCC editor it does what it says, as far as I can tell.

I know when it checks for the tests it uses some kind of strict checker but I’m not exactly sure how it works there.

Here is the third test:


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

Here is the project link:

const recordCollection = {
  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'
  }
};


function updateRecords(records, id, prop, value = "") {
  if (value == "") {
    console.log("Attempting deletion.");
    delete records[id][prop];
    return records;
  } else if (prop != "tracks" && value != "") {
    console.log(`Attempting to reassign the property of ${prop} to ${value}.`);
    records[id][prop] = value;
    return records;
  } else if (prop == "tracks" && value != "" && !records[id][prop]) {
    console.log("Attempting to create new tracks.");
    records[id][prop] = value;
    return records;
  } else if (prop == "tracks" && value != "") {
    console.log("Attempting to add new track.");
    records[id][prop].push(value);
    return records;
  }
}

add this to see what your function has done

updateRecords(recordCollection, 5439, "tracks", "Take a Chance on Me")

console.log(recordCollection[5439])

and consider, is the object formatted as you expect? is there only one string in the tracks array?

Yeah I think so.
Console output:

Attempting to create new tracks.
{ albumTitle: 'ABBA Gold', tracks: 'Take a Chance on Me' }
4

so can you point out where is the array?

Thank you I didn’t notice that it wasn’t an array before.
