Tell us what’s happening:
Hi. Could you, please, explain why it throws the error “TypeError: Cannot read property ‘length’ of undefined”
Your code so far
function filteredArray(arr, elem) {
let newArr = [...arr];
// Only change code below this line
for (let i = 0; i < newArr.length; i++ ) {
for (let j = 0; j < newArr[i].length; j++) {
if(elem === newArr[i][j]) {
newArr.splice(i);
}
}
}
// Only change code above this line
return newArr ;
}
console.log(filteredArray([[10, 8, 3], [14, 6, 23], [3, 18, 6]], 18));
