# Return Largest Numbers in Arrays, help

Tell us what’s happening:

here I have a program that splices away the smallest number in the subarray, leaving only the biggest number.

when I console.log the examples, I was able to achieve the results, but still wouldn’t pass the test.

Your code so far

``````
function largestOfFour(arr) {
// You can do this!
for (let i =0; i < arr.length; i++) {
while (arr[i].length != 1) {
if (arr[i][0] >= arr[i][1]) {
arr[i].splice(1,1);
} else {
arr[i].splice(0,1);
}
}
}

return arr;
}

largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);
``````

I thought maybe its still in a nested array like [[4,27,39, 1001]]

so I tried

``````arr = arr[0].splice(0,4)
``````

and

``````arr = [...arr[0]]
``````

both didn’t work

what am I doing wrong here?
