Javascript hell

In 1997-200x days, when I have been programming in VB3-6 , there was a problem named ”DLL Hell”.

I have been hoping that, with the introduction of .NET, we will escaping this – and I have had my request answered( ok, from .NET 2 )

However, a new problem is for WebDevelopers : JavaScript Hell. Why I am telling that ? Simple :

  1. I have an application that works well in IE 8Star – and uses Json.Stringify to post data. Normally, when I was trying with IE7, it does not work – because JSON.Stringify was not allowed …Of course , solution was adding javascript from .
  2. Same application use jquery 1.4 + 1.1.2 (to can modify dynamically some textboxes) + other js( a date time formatter,jquery ui and others)- . Now , in IE9 RC , jquery1.4 does  not function – and you have to use jquery1.5.1.rc also.Please tell me how to know what modifications the other js files must have( in particular knockout) .

And the mock idea is not solving the issue. You must test either manually , either with an automated test for browser(like Selenium) and testing explicitely in browser version! And I have  speak only about IE, not Firefox and /or Chrome…

If you are a developer, how many javascript do you use? If more than 2 ,welcome to javascript hell!

Star : Please read the requirements from :


Starting with JScript 5.8, by default, the JScript scripting engine supports the language feature set as it existed in version 5.7. This is to maintain compatibility with the earlier versions of the engine. To use the complete language feature set of version 5.8, the Windows Script interface host has to invoke IActiveScriptProperty::SetProperty.

Internet Explorer 8 opts into the JScript 5.8 language features when the document mode for Internet Explorer 8 is “Internet Explorer 8 Standards” mode. For other document modes, Internet Explorer uses the version 5.7 feature set.

JScript 5.8 includes native JavaScript Object Notation (JSON) support and the accessor methods for Document Object Model (DOM) prototypes.
