Image palcement JS

Question

Hi folks
I have one old script and it was working very fine for InDesign CS2. I am learning JavaScript, and I want to convert it in JavaScript. Can any one help me out.
===============
tell application "Adobe InDesign CS3"
tell document 1
set baselineVar to "Yes"
set countVar to 0
set imageCount to 0
set docPath to file path as alias
tell application "Finder"
set imageFolder to folder (choose folder with prompt "Please choose the folder containing the appropriate MathType files")
end tell
activate
set allStories to stories
repeat with s from 1 to count of items of allStories
set theStory to item s of allStories
if class of theStory is story then
set theLim to count of words of theStory
try
repeat with i from 1 to theLim
if word i of theStory contains "<<" then
set theText to contents of word i of theStory as Unicode text
set ImageStyle to "Body"
if name of applied paragraph style of word i of theStory contains "q" then
set ImageStyle to "Test"
end if
if name of applied paragraph style of word i of theStory contains "ans" then
set ImageStyle to "Test"
end if
set theOffset to (offset of "<<" in theText)
set endOffset to (offset of ">>" in theText)
set imageName to characters (theOffset + 2) through (endOffset - 1) of theText as string
set imageFolderPath to ((imageFolder as string) & imageName)
set wholeTag to characters theOffset through (endOffset + 1) of theText as string
if baselineVar = "Yes" then
set baseline shift of characters theOffset through (endOffset + 1) of word i of theStory to -10.2
end if
delete characters theOffset through (endOffset) of word i of theStory
tell theStory
tell word i
tell character theOffset
place imageFolderPath as alias
set countVar to (countVar + 1)
end tell
end tell
end tell
end if
end repeat
end try
end if
end repeat
end tell
activate
if countVar = 0 then
display dialog "No Images were found" buttons "OK" default button 1 with icon 2
else if countVar = 1 then
display dialog "1 lonely Images has been placed." buttons "OK" default button 1
else
display dialog (countVar as string) & " Images have been placed." buttons "OK" default button 1
end if
end tell
===========
Below is the JavaScript for InDesign CS3. Not completed it in process.
=================
//Initializing the front document.
var myDoc = app.activeDocument;
var baselineVar = true;
var countVar = 0;
var imageCount = 0;
var docPath = myDoc.documentPath;
var myGraphicFolder = Folder.openDialog ("Choose Folder which contains images");
var allStories = myDoc.stories;
with (myDoc)

Hi Dave,
Thanks, what side-effect i will get it. I heard that we can do everything with JS as compare to AS.
If really any problem then I will stop myself to work on it. But first I want to know the reason first.
Thanks
