Arguments
=========

This can be omitted at a first reading.  The main point here is that
in JavaScript

#. There is no checking for number and type of arguments.

#. The arguments actually supplied are stored in a special variable,
   called *arguments*.

#. The value of *arguments* is almost, but not exactly, an array.


Test code
---------

.. literalinclude:: /core-javascript-work/tutorial.js
   :language: javascript
   :start-after: start return_arguments
   :end-before: end return_arguments
