Interpreter - JavaScript Interactive Interpreter
</h1>
<div>
<p>
This demo is a JavaScript interpreter. Type some code into
the text input and press enter to see the results. It uses
<a href="http://mochikit.com">MochiKit</a>'s
<a href="../../doc/html/lib/MochiKit/DOM.html">MochiKit.DOM</a>
to manipulate the display. It also supports waiting for
<a href="../../doc/html/lib/MochiKit/Async.html">MochiKit.Async</a>
Deferreds via <tt>blockOn(aDeferred)</tt>.

Notes:
<ul>
<li>
To show the signature of a MochiKit function and link
to its documentation, type help(fn) on any MochiKit
function.
</li>
<li>
To write multi-line code snippets, use the lower text area
and press ctrl-enter or cmd-enter to submit.
</li>
<li>
<tt>function name() {}</tt> syntax might not end up in
window scope, so use <tt>name = function () {}</tt>
syntax instead
</li>
<li>
If you want to stuff something into the output window
other than the <tt>repr(...)</tt> of the expression
result, use the <tt>writeln(...)</tt> function.
It accepts anything that MochiKit.DOM does, so you can
even put styled stuff in there!
</li>
<li>
Use <tt>clear()</tt> to clear the interpreter window.
</li>
<li>
You can use <tt>blockOn(aDeferred)</tt> to wait on a
Deferred. This expression must be used by itself, so
the value must be obtained from <tt>_</tt> or
<tt>last_exc</tt>. Typing any expression will
cancel the Deferred.
</li>
<li>
Up and down arrow keys work as a rudimentary history
</li>
<li>
<tt>_</tt> is the value of the last expression
that was not <tt>undefined</tt>, <tt>last_exc</tt> is
the value of the last unhandled exception.
</li>
</ul>
