it not working at all and it should be right.

Your code so far


[spoiler]function diffArray(arr1, arr2) {
  var newArr = [];
  // Same, same; but different.
  for (var i = 0; i<arr1.length;i++) {
    if (arr2.indexOf(arr1[i]===-1)){
      newArr.push(arr1[i]);
    }
  } 
  for (var j=0;j<arr2.length;j++) {
    if(arr1.indexOf(arr2[j]===-1)){
      newArr.push(arr2[j]);
    }
  }
  return newArr;
  
}





diffArray([1, 2, 3, 5], [1, 2, 3, 4, 5]);[/spoiler]

Hmm… it’s not quite right. Close though!
Here’s the problem:

Inspect that code very carefully. Currently, it checks if the item is -1.

You need to add a console.log before your return statement. For the first test case you are returning the following array:

[ 1, 2, 3, 5, 1, 2, 3, 4, 5 ]

@Steffan153 Instead of giving away the answers, give clues and hints or explain what the existing code does or returns. Let the users figure out the code on their own.
