Collection record

Tell us what’s happening:

Your code so far
i did not get the equation


// Setup

var collection = {
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(object, id, prop, value) {
if (props!=tracks && value!=""){
    return prop == value;
} else if (props ==tracks || {
  
}

}

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

Challenge: Record Collection

Link to the challenge:

I would start this problem by trying to translate these conditions into if statements:

  • 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.

like this:

if (// prop isn't tracks and value isn't empty) {
  // update or set that album's prop to value
}
// ...

That gives you a framework to start on, and then you can focus on turning the comments into real code.
