"JavaScript" is primarily, of course, the language which Tcl's javascript
module targets. 
[[Say a few words on JavaScript as a language.]]

[Zarutian] 28. janúar 2007: Glad to oblige. Javascript is an derivative of [ECMAscript] and is
a cousin to [ActionScript] which is used in Adobe (former Macromedia) [Flash].
Javascript is heavily object oriented prototype based system rather than class based.
And is therefore similar to [Lua] in that regard that objects can obtain new methods and member variables.
[Ajax] is actually Javascript code that relies heavily on XMLPostRequest component and its callbacks.
More about javascript I dont know.

JavaScript and Tcl have a special relation:  both at Sun and Netscape (Mosaic, originally),
the two were in strategic competition.  Roger Binns [[rogerb@rogerbinns.com]]
originally embedded a Tcl interpreter
in the Mosaic browser; "[[d]]etails are in the proceedings of the 2nd WWW [[C]]onference".
He writes about this that, "The audience were in awe
of a demo that printed an entire book based on following the rel links
in web page headers, got everything in the right order, loaded the pages
and printed".

Netscape chose JavaScript, though.

There is also a module in the [tcllib] library of [Tcl] code.
Its purpose is to aid developers in generating [HTML] and JavaScript code.
Related modules are [ncgi] and [html].

Documentation can be found at http://tcllib.sourceforge.net/doc/javascript.html .

Examples of use of this code are encouraged.

[NEM] If you want to evaluate JavaScript code from Tcl, then there are a couple of options.
Firstly, [hv3], the web-browser built on top of [TkHTML] comes with a binding to the SEE
ECMAScript Interpreter library [http://tkhtml.tcl.tk/hv3.html]. 
Secondly, I also have a very quick/simple binding to the
NJS interpreter library available from [http://www.cs.nott.ac.uk/~nem/tcl/]. 

[jdc] Another option is http://code.google.com/p/tcljs/%|%tcljs%|%. It can be used to embed spidermonkey in a Tcl application. 

It can be used in combination with package http://code.google.com/p/tcljspac/%|%tcljspac%|% to process `proxy.pac` files.

Yet another option for bindings to SpiderMonkey [http://aolserver.cvs.sourceforge.net/viewvc/aolserver/nsjsapi/]

Anyone who has read this far will probably want to know about Zombie [http://labnotes.org/2010/12/30/zombie-js-insanely-fast-full-stack-headless-testing], created for automatic testing of JavaScript-coded applications (more than that, really; it also knows about [CSS], ...).  It's of broader interest, though, mostly in directions where Tclers swarm:  automation, [Web scraping], [DOM] analysis, ...  Zombie is [open source], of course, and a nice model for at least a few techniques that are useful in Tcl-oriented [testing] code.
