Basic JavaScript - Record Collection

[jake613]

Tell us what’s happening:
Describe your issue in detail here.

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

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

why cant i use dot notation to access all this?
i took a look at the solution and its very similar to what i wrote except it uses bracket notation instead.

thanks in advance!

Review this lesson: https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures/basic-javascript/accessing-object-properties-with-variables

Dot notation can only be used with literal property names, not variables.

[jake613]

so in this record case, when calling the function is each parameter considered a variable even if it is also a literal property name? or am i dumb and it’s because the literal property name in the called function is a string?

[JeremyLT]

Function parameters are variables. You aren’t looking for the literal prop records.id

That’s where I was confused thank you!
