Record collection

[95trevorthompson]

These are the objectives:

• After updateRecords(recordCollection, 5439, “artist”, “ABBA”), artist should be the string ABBA

• 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.

• After updateRecords(recordCollection, 2548, “artist”, “”), artist should not be set

• After updateRecords(recordCollection, 1245, “tracks”, “Addicted to Love”), tracks should have the string Addicted to Love as the last element.

• After updateRecords(recordCollection, 2468, “tracks”, “Free”), tracks should have the string 1999 as the first element.

• After updateRecords(recordCollection, 2548, “tracks”, “”), tracks should not be set

• After updateRecords(recordCollection, 1245, “albumTitle”, “Riptide”), albumTitle should be the string Riptide

This is my code:

// Setup
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'
  }
};

// Only change code below this line
function updateRecords(records, id, prop, value) {
  if (prop !== "tracks" && value.length !== 0) {
    recordCollection[id][prop] = value;
  } else if ( prop == "tracks" && recordCollection[id].hasOwnProperty("tracks") == false) {
    recordCollection[id].tracks = [];
    recordCollection[id].tracks.push(value);
  } else if ( prop == "tracks" && value.length > 0) {
    recordCollection[id][prop].push(value);
  } else if ( value.length < 1) {
    delete recordCollection[id][prop];
  }
  return records;
}

updateRecords(recordCollection, 5439, "artist", "ABBA");
updateRecords(recordCollection, 5439, "tracks", "Take a Chance on Me");
updateRecords(recordCollection, 2548, "artist", "");
updateRecords(recordCollection, 1245, "tracks", "Addicted to Love");
updateRecords(recordCollection, 2468, "tracks", "Free");
updateRecords(recordCollection, 2548, "tracks", "");
updateRecords(recordCollection, 1245, "albumTitle", "Riptide");

console.log(recordCollection);

This is what the console logs:

// console output
{ '1245': 
   { artist: 'Robert Palmer',
     tracks: [ 'Addicted to Love' ],
     albumTitle: 'Riptide' },
  '2468': 
   { albumTitle: '1999',
     artist: 'Prince',
     tracks: [ '1999', 'Little Red Corvette', 'Free' ] },
  '2548': { albumTitle: 'Slippery When Wet' },
  '5439': 
   { albumTitle: 'ABBA Gold',
     artist: 'ABBA',
     tracks: [ 'Take a Chance on Me' ] } }

But, freeCodeCamp recognizes my solution as incorrect. Can anyone please help me with this? I’m new to coding.

I was expecting to get to the next level in freeCodeCamp, bc it appears as though my solution works.

You should not reference variables outside the scope of your function.

thanks man! I appreciate it. That makes a lot of sense!
