Basic JavaScript - Record Collection

[TTEOTM]

Tell us what’s happening:
I don’t understand what I am doing wrong here , only one test passes so far.

Your code so far

// 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 (value==''){
    delete records[prop];

  }
  else if(prop!='tracks' && value!=''){
    records[prop]=value;
  }
  else if(prop=='tracks' && value!=''){
    if(records.hasOwnProperty(prop)){
      records[prop]+=[value];

    }
    else{
      records[prop]=[value];
    }

  }
  return records;
}

updateRecords(recordCollection, 5439, 'artist', 'ABBA');

records[prop]+=[value];

I suspect this line doesn’t do what you think?

[TTEOTM]

add to the existing array ?

update:it’s still not working in freecodecamp editor(the very first test)
However in another editor it gives:

The second test also works :

What is ‘it’? What’s your updated code?

I’ve noticed that you don’t seem to be using id anywhere? It’s given as an argument, so you’re intended to use it.

When I run this code above I get an error message “collection not defined” Can you please shed some light on how to define collection.
