Tell us what’s happening:
Hello,

Why the code is still in a error?

Thanks.

Your code so far


function filteredArray(arr, elem) {
  let newArr = [];
  // change code below this line
  newArr = [...arr]
  for (let i = 0; i < newArr.length; i++) {
    if (newArr[i].indexOf(elem) != -1) {
      delete newArr[i]
    }
  }
  // change code above this line

  return newArr;  
}

// change code here to test different cases:
console.log(filteredArray([ ["amy", "beth", "sam"], ["dave", "sean", "peter"] ], "peter"));

Thanks Randellawson.

Yes, you are right, your solution is better with push()
