Recordcollection update

I’ve done all the tasks but there is one error. What did I miss?

  **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 (prop !== "tracks" && value !== "") {
  records[id][prop] = value;
} else if (prop !== "tracks" && records[id].hasOwnProperty("tracks") === false) {
  record[id][prop] = value;
} else if (prop === "tracks" && value !== "") {
  records[id][prop].push(value);
} else if (value === "") {
  delete records[id][prop];
} return records;
} 

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

Challenge: Record Collection

Link to the challenge:

This is the following case:

  • If prop is tracks but the album doesn’t have a tracks property, create an empty array and add value to it.

like this?

else if (prop === “tracks” && value !== “”) {
records[id][prop].push(value)}

You can’t push onto an array that does not exist… That case is where the array exists.

This part though… (Also, this part needs a value="" check)

I already correct prop === “tracks”

how do I add empty array? or can you remind me which course step I should look back?

I swear I’m losing brain cells every time I thought it’s impossible :smiley:

create an array, records[id][prop] = ;
give the array a value. records[id][prop].push(value);

That’s it!
I’m lmao of how stupid I am. Now I can sleep! thanks, fcc. see you tomorrow!

It’s hard stuff. Good work figuring it out!
