--description--

You will be provided with an initial array as the first argument to the destroyer function, followed by one or more arguments. Elimina todos los elementos del arreglo inicial que tengan el mismo valor que estos argumentos.

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.
