Basic JavaScript - Record Collection

Tell us what’s happening:

After updateRecords(recordCollection, 2468, "tracks", "Free") , tracks should have the string 1999 as the first element.
Here the string ‘1999’ is not assigning as the first element of the “tracks” array. How can I solve this? please help.

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[id][prop];
  }else if(prop!="tracks" && value != ""){
    records[id][prop] = value;
  }else if(prop=="tracks" && value != ""){
    if(id.hasOwnProperty("tracks")==false){
      records[id][prop] = [];
    }
    records[id][prop].push(value);
  }else if(prop=="tracks" && value == "Free"){
    if(id.hasOwnProperty("tracks")==false){
      records[id][prop] = [];
    }
    records[id][prop].unshift("1999");
    records[id][prop].push(value);
  }
  return records;
}

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

Welcome to the forum @mdtazimmiah20126913

  }else if(prop=="tracks" && value == "Free"){

    records[id][prop].unshift("1999");

You have hard coded two parameters.

Try using the arguments listed in the instructions.

The code should be able to modify the record collection based on user input.

Happy coding
