Basicamente eu faço o código no replit e se funcionar eu ponho no console do FCC, mas no replit ele está funcionando perfeitamente, porém no FCC não. Porque? Testei com as arrays fornecidas no desafio e todas apresentaram o resultado correto, porém meu código não é aceito
**Meu código:**
function largestOfFour(arr) {
sortedArr = []
for(let i = 0; i <= arr[0].length; i++){
let arr1 = arr[i].sort((a, b) => a - b)
sortedArr.push(arr1.pop())
}
return sortedArr;
}
largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);

just played a bit and don’t think you want the [0] in arr.length
function largestOfFour(arr) {
let sortedArr = []
for(let i = 0; i < arr.length; i++){
arr[i]=arr[i].sort((a, b) => a - b)
sortedArr.push(arr[i].pop())
}
return sortedArr;
}
largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);
but i wondered: if the .sort sorts the elements in place anyway, would we rather use a new variable here? does it matter if that’s how .sort works anyways? anyone?
I would say that usually you would not want to modify the arrays/objects passed into a function unless it was specifically designed to do that for some reason. So yes, your question is a good one and if you are going to sort the subarrays you should probably clone them first. The even better choice would be to use a method that didn’t require you to use a temp array in the first place.
Yes, exactly. JS provides several methods that allow you to do this in a variety of ways. The one that jumps out to me right away allows you to find the max value in a list of numbers.
