JScript - Managed or Native, JavaScript, ECMAScript - What's what? And references ...

Being a late entrant into the group, I always had questions regarding what’s what of JScript - Managed or Native, JavaScript, ECMAScript. Though I could find quite a lot of information at varied places, I thought it might be a good idea to compile a small blog around the subject – so that we have the information collated at one place. And here is what I ended up with:

· The World of JScript, JavaScript, ECMAScript …

· Difference between JScript, JScript.NET and Managed JScript

· Some Quick JScript References

Putting links at the JScript team blog site just in case somebody finds them useful.

Thanks

Javascript Intellisense in VS 2008 for Silverlight 1.0

Sameerch — Tue, 07 Aug 2007 13:52:00 GMT

Javascript Intellisense is one of the major improvements in Visual Studio 2008 Beta 2. There is a nice project that extends the javascript intellisense experience for Silverlight 1.0 by Justin. With this extension, developers will experience full javascript intellisense in VS 2008 while developing applications for Silverlight 1.0.

As you can see, you get much more intellisense. Follow up his blog for more.

Introducing Managed JScript

jitu — Mon, 07 May 2007 08:34:00 GMT

It's finally released and I can blog about it. Have been waiting to write about it for some time now and now that it’s out, can talk about it.
Scott Guthrie in his keynote at MIX this week, announced that we are implementing a new version of JSscript implementation to run on top of the .NET platform. This would be called Managed Jscript. Managed Jscript will run on the new DLR, which also got announced at MIX, and interops well with other languages on DLR. So now the Jscript code, works well with not only C#, but also with IronPython , IronRuby, VB among other languages.

And this with the Silverlight platform, running cross browser, cross platform, would mean that the AJAX and other applications that were written with Jscript, would become more easier to write.

Checkout the cool talk about DLR and how various languages interop from Jim Hugunin and John Lam. DLRConsole sample is a cool sample to try the new Managed Jscript and also it’s interop with other languages.

Managed JScript announced

At MIX07 we released a new implementation of JavaScript on top of Dynamic Language Runtime (DLR) as part of Silverlight 1.1 Alpha release. The brand new JavaScript implementation code named “Managed JScript” brings all the power of managed world to JavaScript developers. This release provides cross-language support and access to the .NET Framework along with ECMAScript Edition 3 feature set. We are working to make sure that Managed JScript is a first class language on top of DLR.

Although both Managed JScript and JScript.NET are running on top of .NET Framework, they are different implementations. Managed JScript is a brand new implementation based on infrastructure provided by DLR. It is an implementation of ECMAScript Edition 3 with added support for CLR and DLR. Being based on DLR, it nicely interoperates with other dynamic languages. Managed JScript doesn’t support JScript.NET Classes, typed variables and generation of assemblies.

A QuickStart guide for programming Silverlight using Managed JScript and other dynamic languages is available at Silverlight site. There are some cool samples available at http://www.codeplex.com/dynamicsilverlight. You are welcome to add your DLR based samples on CodePlex. Also Jim Hugunin is now blogging about DLR’s design and other details. Jim Hugunin and John Lam gave a very interesting talk at MIX showing the power of DLR and Silverlight by gluing together code from different languages and creating a brand new sample.

Managed JScript is also available as part of Microsoft ASP.NET Futures (May 2007) for use as server side dynamic language. A walkthrough on using Managed JScript and other dynamic languages in ASP.NET is available.
