JavaScript
1

Tell us what’s happening:
Hi, I am trying to push an element in an array but it is not working and, I checked the syntax.

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"
    }
};
// Keep a copy of the collection for tests
var collectionCopy = JSON.parse(JSON.stringify(collection));

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

// Alter values below to test your code
updateRecords(5439, "artist", "ABBA");

I see an error here. You need 1 more closing parentheses.

thank you. I have read the information about bracket notation and it works
