# --description--

You will be provided with an initial array as the first argument to the `destroyer` function, followed by one or more arguments. Entferne alle Elemente aus dem Ausgangsarray, die den gleichen Wert wie diese Argumente haben.

The function must accept an indeterminate number of arguments, also known as a variadic function. You can access the additional arguments by adding a rest parameter to the function definition or using the `arguments` object.

# --hints--

`destroyer([1, 2, 3, 1, 2, 3], 2, 3)` sollte `[1, 1]` zurückgeben.

```js
assert.deepEqual(destroyer([1, 2, 3, 1, 2, 3], 2, 3), [1, 1]);
```

`destroyer([1, 2, 3, 5, 1, 2, 3], 2, 3)` sollte `[1, 5, 1]` zurückgeben.

```js
assert.deepEqual(destroyer([1, 2, 3, 5, 1, 2, 3], 2, 3), [1, 5, 1]);
```

`destroyer([3, 5, 1, 2, 2], 2, 3, 5)` sollte `[1]` zurückgeben.

```js
assert.deepEqual(destroyer([3, 5, 1, 2, 2], 2, 3, 5), [1]);
```

`destroyer([2, 3, 2, 3], 2, 3)` sollte `[]` zurückgeben.

```js
assert.deepEqual(destroyer([2, 3, 2, 3], 2, 3), []);
```

`destroyer(["tree", "hamburger", 53], "tree", 53)` sollte `["hamburger"]` zurückgeben.

```js
assert.deepEqual(destroyer(['tree', 'hamburger', 53], 'tree', 53), [
  'hamburger'
]);
```

`destroyer(["possum", "trollo", 12, "safari", "hotdog", 92, 65, "grandma", "bugati", "trojan", "yacht"], "yacht", "possum", "trollo", "safari", "hotdog", "grandma", "bugati", "trojan")` sollte `[12,92,65]` zurückgeben.

```js
assert.deepEqual(
  destroyer(
    [
      'possum',
      'trollo',
      12,
      'safari',
      'hotdog',
      92,
      65,
      'grandma',
      'bugati',
      'trojan',
      'yacht'
    ],
    'yacht',
    'possum',
    'trollo',
    'safari',
    'hotdog',
    'grandma',
    'bugati',
    'trojan'
  ),
  [12, 92, 65]
);
```

# --seed--

## --seed-contents--

```js
function destroyer(arr) {
  return arr;
}

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

# --solutions--

```js
function destroyer(arr) {
  var hash = Object.create(null);
  [].slice.call(arguments, 1).forEach(function(e) {
    hash[e] = true;
  });
  return arr.filter(function(e) { return !(e in hash);});
}

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