You are given an object literal representing a part of your musical album collection. Each album has a unique id number as its key and several other properties. Not all albums have complete information.

You start with an updateRecords function that takes an object literal, records , containing the musical album collection, an id , a prop (like artist or tracks ), and a value . Complete the function using the rules below to modify the object passed to the function.

  • Your function must always return the entire record collection object.
  • If prop isn’t tracks and value isn’t an empty string, update or set that album’s prop to value .
  • 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.
  • If value is an empty string, delete the given prop property from the album.

      **// 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("track") === false){
    var emptyArr = [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');**

What is going on here?

You can’t use dot notation with a variable holding a property name.
