splice method returns an error: is not a function

I have been trying to make the code below work, which is a part of deletion function. However, the splice method inside the for-loop keeps returning an error when it's run.

Can anyone please give me a solution to this problem?

let games = JSON.parse(localStorage.getItem('games'));

for (let i =0; i < games.length; i++) {
    if (games[i].gName == gName) {
        console.log('found it');
        games[i].splice(i, 1);
        //Uncaught TypeError: games[i].splice is not a function
    }
}
Solution

  • I think the splice function returns an error because games[i] is an object, not an array. If you want to use splice on the array, just remove the [i] part. games.splice(i, 1);

    Also you can use for (i in games) as a shorthand for for (let i =0; i < games.length; i++);
