Tell us what’s happening:
Hello, this is my code and i get this error: TypeError: arr[i] is undefined. The reason is the delete operator somehow, because without it I get no error. How should i fix it, and why do i get the error?
Your code so far
function filteredArray(arr, elem) {
let newArr = [];
// Only change code below this line
for (let i = 0; i < arr.length; i++){
for (let b = 0; b < arr[i].length; b++){
if (arr[i][b] == elem){
console.log(arr[i][b])
delete arr[i];
}
}
}
// Only change code above this line
return newArr;
}
console.log(filteredArray([[3, 2, 3], [1, 6, 3], [3, 13, 26], [19, 3, 9]], 3));
