Largest Numbers in Arrays

JavaScript
1

My solution works but FreeCodeCamp did not accept my answer. I tested it on all parameters required. It produces the result in the array format that it is requesting. Please help :slight_smile:

var largestArr = [];
function largestOfFour(arr) {
// You can do this!
for (var i = 0; i < 4; i++) {
arr[i] = arr[i];
// console.log(arr[0]);
// console.log(arr[1]);
// console.log(arr[2]);
// console.log(arr[3])
// console.log(arr[i][0]);;
arr[i].sort(function(a,b){
return a < b;
});
console.log(arr[i][0]);
answer = arr[i][0];
largestArr.push(answer);

  	console.log(largestArr);
  }
  		 console.log(largestArr);
  		 return largestArr;
  	 
  
}

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

You are setting largestArr outside the function and you are not clearing it for every function call. So your function will only work correctly once.

thanks BenGitter, one more question about your answer:

what does it mean when you say ‘not clearing it for every function call’ ?

the easiest way to fix your problem is by placing the var largestArr = []; inside the function. But you could also clear the array / empty it:

var largestArr = [];
function largestOfFour(arr){
  largestArr = [];  // empty it
  ...
}

This way largestArr is emptied every time you run the function.
