--description--

You will be provided with an initial array as the first argument to the destroyer function, followed by one or more arguments. これらの引数と同じ値を持つすべての要素を最初の配列から削除してください。

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) は [1, 1] を返す必要があります。

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

destroyer([1, 2, 3, 5, 1, 2, 3], 2, 3) は [1, 5, 1] を返す必要があります。

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

destroyer([3, 5, 1, 2, 2], 2, 3, 5) は [1] を返す必要があります。

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

destroyer([2, 3, 2, 3], 2, 3) は [] を返す必要があります。

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

destroyer(["tree", "hamburger", 53], "tree", 53) は ["hamburger"] を返す必要があります。

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") は [12,92,65] を返す必要があります。

assert.deepEqual(
  destroyer(
    [
      'possum',
      'trollo',
      12,
      'safari',
      'hotdog',
      92,
