Basic JavaScript - Record Collection

JavaScript
1

Hello Everyone,

I am stuck in this challenge. I am having a difficult time understanding what to use for the two bullet points:

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

I have tried to use the following if…else if statements for my function but it is still showing them as incorrect. I would appreciate any help. Thanks in advance!

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

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

This is a big problem in your code. The requirements say things like

If prop is tracks

That is referring to the actual prop variable
