Basic Algorithm Scripting - Seek and Destroy

Basic Algorithm Scripting - Seek and Destroy


Hey guys, I think I’m stuck here and I really need some help.

I came up with the following Code:
(I’m pretty sure there is a much simpler way to solve this than mine, but I wanted to try it myself before looking into the wiki.)

`function destroyer(arr) {

return arr.filter(function(a){
var matched = 0;

for (var i = 1; i < destroyer.arguments.length; i++){
  if (a == destroyer.arguments[i]) {

if (matched === 0) {
  return true;

return false;



destroyer([1, 2, 3, 1, 2, 3], 2, 3);`

In my opinion it works just fine.
The code removes all elements from the initial array that are of the same as the given arguments.

Here is the

The FCC Console is always showing me : TypeError: Type Error

I hope someone knows an answer how I am able to pass the Challenge or how to get my Code to work.


This is my solution, it looks different from yours:


In your code, I stored the destroyer function’s arguments in a variable, then used that in the inner function instead.

var destroyerArgs = Array.from(arguments);

// ...

for (var i = 1; i < destroyerArgs.length; i++)

// ...

I think I’ve read somewhere that referencing arguments via its function’s name is not a good idea.


Thank you @kevcomedia, putting the arguments in an Array made my Code work :slight_smile:
