Tell us what’s happening:
I’m not sure why my code is returning " Cannot read property ‘length’ of undefined" any tips?
Your code so far
function filteredArray(arr, elem) {
let newArr = [];
// change code below this line
for (let i = 0; i < arr.length; i++){
for (let j = 0; j <arr[i].length; i++){
if (arr[i][j] === elem) {
newArr = arr.splice(i, 1);
--i;
}
}
}
// 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));
