Return Largest Numbers in Arrays in javascript

Tell us what’s happening:

I want the largest value from each of the subarray’s and push that values into a brand new array but I don’t know what’s wrong with this code

Your code so far

function largestOfFour(arr) {
let newarr = []
for(let i=0; i<arr.lentgh; i++){
return newarr;

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