Return Largest Numbers in Arrays
Return an array consisting of the largest number from each provided sub-array. For simplicity, the provided array will contain exactly 4 sub-arrays.

Remember, you can iterate through an array with a simple for loop, and access each member with array syntax arr[i].

Remember to use Read-Search-Ask if you get stuck. Write your own code.

function largestOfFour(arr) {
 for(var i=0 ; i < arr.length; i++) {
  	arr[i].sort(function(a,b) {
  		return b-a;
  	});
  }
  
  //console.log("arr: ", arr)
  
  	var arr1 = [];
  	for (j=0; j<arr.length; j++){
  		arr1.push(arr[j][0]);
  	}
  	
  	return arr1;
}

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