Describe your issue in detail here.
Hi,
I was wondering if someone could help me understand the solution code. If the element is not found in the array, why would we push the array into a new array?
My understanding of the problem was that if the element was found, we would remove it. I just don’t understand how the solution code accomplishes this. I’ve researched it as best I can and I just don’t get it. Any insight would be appreciated.
Your code so far
function filteredArray(arr, elem) {
let newArr = [];
// Only change code below this line
for (let i = 0; i < arr.length; i++) {
if (arr[i].indexOf(elem) == -1) {
newArr.push(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));
