javascript - 将嵌套数组和元素作为参数的函数，返回一个新数组，如果嵌套数组不包含元素，它将把它推送到 newArr

Question

function filteredArray(arr, elem) {
  let newArr = [];
  for (let i = 0; i < arr.length; i++) {
    for (let j = 0; j < arr[i].length; i++) {
      if (arr[i][j] != elem) {
        newArr.push(arr[i]);
      }
    }
  }
  return newArr;
}

console.log(filteredArray([
  [3, 2, 3],
  [1, 6, 3],
  [3, 13, 26],
  [19, 3, 9]
], 3));

我应该如何删除该错误？如果嵌套数组不包含元素，它会将其推送到 newArr。

            }
        }
    }
    return newArr;

    [19, 3, 9]
