Where is the Javascript Compiler ?

[Mel Smith]

Hi:

On my own machine running IE7, where is the JavaScript executable, or
DLL ?

Where is the source on which Javascript is built ?

What language was used to build Javascript (C, C++, or what) ?

Is the source available anywhere for 3rd parties (like me) to examine ?

Will I ask anymore stupid questions ? (Answer: Yes, probably )

Thanks !

I suppose you mean Java/ECMAScript Interpreters, right? Since Chromium
and Firefox are open source, you can examine the source code. Since
Internet Explorer is only available as (closed-source) executable you can't.

This is already pretty stupid. Can't wait for your all-time low...

somewhere on your C:-drive

somewhere on the internet

i dont car about this one, because the build language is more important
than the language it was build in/with

here is some source, but its a different implementation than the one in
IE7, (at least, i think it is.....)
http://www.ecmascript.org/index.php

None. It's a hardware problem.

On an HDD. More than that one cannot necessarily say, because of
options as to what goes where.

But, on my WinXP sp3 with IE8, at a CMD prompt,

C:\WINDOWS\system32>HUNT *.dll * hscript e | sort
2006/02/28-13:00:00 SCRIPTPW.DLL 10240 .....a..
2008/04/14-01:11:52 DMSCRIPT.DLL 82432 .....a..
2009/12/09-06:53:44 JSCRIPT .DLL 726528 .....a..
2010/03/10-07:15:52 VBSCRIPT.DLL 420352 .....a..

which may be a guide. The presence of DMSCRIPT.DLL is interesting; an I
infested by My Library?

Where is the source on which Javascript is built ?

Seattle, Redmond, or thereabouts, probably.

What language was used to build Javascript (C, C++, or what) ?

Who knows what may have escaped? Microsoft will make the source
available to you for a sufficient sum, but it may be multiple M$, G$, or
T$; and you will need more lawyers than you can afford.

I run IE 7 on my Win XP Pro (sp3) machine. So, I'll look on mine and
sniff around.

btw, I downloaded 'Spidermonkey' Javascript source from Mozilla this
morning. Will be looking at it over the next while.

Thank you and the other responders.

Dr. S.:

My IE7 has a jscript.dll made on 08/13/2009 (before yours), and is sized
at 512,000 (significantly smaller than yours).

I guess that your IE8 has a bigger/better Javascript implementation.

It would be nice if somebody could de-compile this executable. Fat
chance

Probably faster and more productive to create a half ass
implementation from the spec. Better yet, look at the numerous open
source (and superior) implementations available on the interwebs.

If I look at the file entry starting from "My Computer" and hover on it,
I see its internal version number 5.8.6001.22960; right click then
Properties shows a little more.

I don't recall any JavaScript bugs in Firefox; if you were looking at
other sources, <URL:http://www.merlyn.demon.co.uk/js-datex.htm> might
show you some to look out for. My ISP's server has been mended.

Dr. S:

My jscript.dll has the following info:

Internal Version No.: 5.7.6002.22145
Created on: May 9, 2008

Interesting !

Thanks for the follow up.
