Counters example
================

Goal
----

The goal is to create a web page which contains several independent
counters.  Each time a counter is clicked, it is incremented.  Here's
you can `try out a working example
<./core-javascript-work/counters.html>`_ of what's wanted.

Below is the complete code of this example.  To simplify the matter,
it is completely self-contained.  It uses no library code, other than
the definition of *SimpleClass*.

In general library code is a good idea.  This example is designed to
teach you the basics of JavaScript, and not the use of a library.  We
hope that what you learn here will help you choose a library, and
build libraries of your own.
