Python vs. VBScript vs. JavaScript in context of Windows ScriptingHost?

[John Benson]

Hi, I'm in a tightly-secured environment where I may not be allowed to use
Python for some scripting work, and may have to fall back on what came with
Windows 2K.

I'm cracking "VBScript in a Nutshell" from O'Reilly, and have found a number
of disappointments:

* can't find "Introspection" in the Index
* no record types, just numerically-indexed arrays, so record handling is
kludgy
* zero-based array indexing (this is Basic?)
* script debugger is slanted towards debugging VBScript inside Internet
Explorer
* "on error resume next" pretty much sums up the error handling
* truly bizarre use of parentheses to override argument passing by reference
in a completely nonobvious context

It looks pretty weak compared to Python, but I may not have the luxury of
Python in this situation.

Here's the question: If JavaScript is available to me within the Windows
Scripting Host, can it do everything that VBScript can? My JavaScript
documentation (the O'Reilly rhino book) is "client-side scripting"-centric,
and as such accepts the limitations on file manipulation imposed by the
client-side security scruples. Can anyone recommend a reference on
JavaScript as an expedient replacement for Python within the context of the
Windows Scripting Host?

I know this isn't the real concern of this forum, but I know there are a lot
of experienced generalists out there whose experience I would like to tap.
Thanks in advance for any responses.

Yes, Andy's reply is right on target. JavaScript can access all of the same
WSH object model as VBScript. I think you'll find JavaScript to be a much
more satisfactory language than VBScript.

Flanagan's book (the rhino book) will still be useful. All of Parts I and
III (Core JavaScript and Core JavaScript Reference) apply to JavaScript in
any environment: browser, WSH, Adobe Acrobat or Photoshop, you name it.

Microsoft has a very good Windows Script site with information on Script,
the WASH object model, etc. here:

http://www.msdn.microsoft.com/scripting

That plus Flanagan's book should be just about everything you need.

That, of course, should say "WSH object model." Dang spelling checker went
and changed it before I noticed! :-)

comp.lang.python:

* zero-based array indexing (this is Basic?)
BASIC has ALWAYS had zero-based indexing... BUT it played a game
with the users...

dim a(10)

allocates ELEVEN elements, indexed 0..10, and most people never realized
the 0 index was available.
