Basic Javascript Record Collection test failing

JavaScript
1

Tell us what’s happening:

The challenge is not accepting my solution because one test is failing. But when I log that test to the console, the output is exactly what it is looking for (as far as I can tell).

When I log the following, it says the tracks property should not be set (failed test)
console.log(updateRecords(2548, “tracks”, “”));

but my output is: ‘2548’: { album: ‘Slippery When Wet’, artist: ‘Bon Jovi’ },

So I’m not seeing why this test fails. There is no tracks property in it. Any thoughts from anyone out there? I assume I’m making a dumb mistake somewhere, but for the life of me I cannot find it.

Your code so far


// Setup
var collection = {
2548: {
  album: "Slippery When Wet",
  artist: "Bon Jovi",
  tracks: [
    "Let It Rock",
    "You Give Love a Bad Name"
  ]
},
2468: {
  album: "1999",
  artist: "Prince",
  tracks: [
    "1999",
    "Little Red Corvette"
  ]
},
1245: {
  artist: "Robert Palmer",
  tracks: [ ]
},
5439: {
  album: "ABBA Gold"
}
};

// Only change code below this line
function updateRecords(id, prop, value) {
  if (prop != "tracks" && value != "") {
    collection[id][prop] = value;
  } 
  
  else if (prop === "tracks" && collection[id].hasOwnProperty("tracks") === false) {
    collection[id]["tracks"] = [];
    collection[id]["tracks"].push(value);
  } 
  
  else if (prop === "tracks" && value != "") {
    collection[id][prop].push(value);
  } 
  
  else if (value === "") {
    delete collection[id][prop];
  }

return collection;
}

// Alter values below to test your code

console.log(updateRecords(2548, "tracks", ""));
//console.log(updateRecords(2548, "artist", ""))

Try resetting the challenge and putting your solution in again. It is passing all tests when I run your code.

Thank you very much. That did fix it. I’ve reloaded the page many times just in case the back-end container expired (happens a lot on Codecademy), but I didn’t try resetting the whole thing. I’ll remember this for future reference.
