Welcome to the forum @JlaYmix

It looks like you added code from the example.

> [@JlaYmix](#):
>
> ```auto
> let rows = [1, 2, 3];
> rows[2] = 10;
> console.log(rows);
> console.log(rows);
> 
> ```

Please remove the `rows` variable and declaration from the above code block.

Also remove one of the console logs.

Happy coding
