The code does not seem to work at all

Your code so far


// Setup
var collection = {
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(object, id, prop, value) {
if(prop!=='tracks' && value!== ""){
object[id][prop]=value;
}else if (prop==="traks" && !object[id].hasOwnProperty(tracks)){
  object[id][prop]=value;
}else if(prop==="tracks" && value!==""){
  obejct[id][prop].push(value);
}else if (value===""){
  delete object[id][prop];
}

return object;
}

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

Can you please elaborate on the problem and what you trying is?

Just eyeballing this I can see some obvious typos in variable and property names (obejct and traks). Not sure if that’s all that’s needed to get this working for you but it’s a start :slight_smile:

when using “if” the last one should be “else”
change it to this:

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

instead of this:

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

that might be the problem :slightly_smiling_face:

I think you are getting a “tracks is undefined” error from here

can you imagine why?
