<p>Jtalk is an implementation of the <a href="http://en.wikipedia.org/wiki/Smalltalk">Smalltalk</a> language that runs on top of the <a href="http://en.wikipedia.org/wiki/Javascript">JavaScript</a> runtime. It is designed to make client-side development faster and easier.</p>
<p>Jtalk is written in itself, including the parser and compiler. Jtalk compiles into efficient JavaScript, mapping one-to-one with the equivalent JavaScript. There is no interpretation at runtime.</p>
<p>Try a <button onClick="smalltalk.Browser._open()"> Class browser</button> right now!</p>

<p class="warning">This documentation is a work in progress.</p>
<p class="information">Jtalk is a young piece of code and evolves quickly. Some features are still incomplete and you may very well encounter bugs.</p>
<p>Jtalk is an implementation of the Smalltalk-80 language. It allows developers to write client-side heavy web applications in Smalltalk. Jtalk includes an integrated development environment with a class browser, workspace and transcript.</p>
<p>Jtalk includes the following features:</p>
<ol>
<li>It is semantically and syntaxically equivalent to <a href="http://www.pharo-project.org">Pharo Smalltalk</a> (the implementation considered as the reference)</li>
<li>It is written in itself and compiles into efficient JavaScript</li>
<li>A canvas API similar to <a href="http://www.seaside.st">Seaside</a> to generate HTML</li>
<li>A <a href="http://www.jquery.com">jQuery</a> binding</li>
</ol>

<h3 id="counter-example">3. The counter example <a href="#counter-example">¶</a></h3>
<p>The following example is the traditional Seaside-like multi-counter application. The buttons at the bottom of each counter increase or decrease the counter.</p>
<div id="counters"></div>
<script type="text/javascript">
jQuery(document).ready(function() {'#counters'._asJQuery()._append_(smalltalk.Counter._new())._append_(smalltalk.Counter._new())});
</script>
<p>Open a <button onclick="smalltalk.Browser._openOn_(smalltalk.Counter);">browser</button> on the <code>Counter</code> class in the <code>Canvas</code> class category.
<p>Each Jtalk widget is a subclass of <code>Widget</code>. A widget is a graphical component. The <code>#renderOn:</code> method is used to generate HTML using the HTML canvas.</p>
