I'm trying to access a specific element in an array, but I'm only getting the first one. Any help with pointing out my error is appreciated.

```
let testArr = [[1, 2, 3],[4, 5, 6]];
const printArr = (someArr, i) => alert(someArr[i]);
printArr(testArr, [0][0]);

```

Expected Output

```
1

```

Actual Output

```
1, 2, 3

```
