Why not working? - Iterate Through All an Array's Items Using For Loops

Tell us what’s happening:
Hey, please let me know how to simplify this code and make it solve the problem.

Your code so far


function filteredArray(arr, elem) {
  let newArr = [];
  // change code below this line
for (let i=0;i<arr.length;i++){
let delElem = arr[i].indexOf(elem);
arr[i].splice(delElem, 1);
newArr.push(arr);
}
  // change code above this line
  return newArr;
}

// change code here to test different cases:
console.log(filteredArray([[3, 2, 3], [1, 6, 3], [3, 13, 26], [19, 3, 9]], 3));

It looks like at the end of each iteration in for loop, you are for somereason pushing the entire original array to newArr, which I am not sure you didn’t intend.

How about you you just splice off arrays that contain particular elem only and keep original array instead of pushing subarrays into newArr?
