I\'m interested to know who uses JScript.Net and for what sort of applications. Whenever I\'m reading MSDN .Net documentation, I always notice the JScript samples but in all
I use it quite a lot, almost exclusively, for ASP.NET and related web-stuff.
You can use it for pretty much all the stuff you can use the other .NET languages for. It makes MSIL, just like the others ;) Compiled with the "fast" option which turns of some of the native javascript traits, like prototype extensions and eval, it performs just like any other code on the CLR.
It's certainly not a full-fledged member of the family, in the sense that it seems somewhat left behind in .NET 1.1 in terms of features, the tool support is non-existant, and the documentation is downright appaling. That's part of why I like it so much, actually, makes me feel like I'm programming.
If you have a lot of (j)scripts lying around that needs to be converted to .NET, this is the obvious choice as you will usually need very little rewriting for that to work. Otherwise there's no particular reason for choosing JScript.NET over any other .NET language, and many reasons not to.
It all comes down to personal preferences since it all ends up as the same CLR code, regardless of language. I find JScript.NET easy-going, natural to write and with a flexible simplicity like no other language I tried, so I use that until I encounter a problem that the language just can't handle. Hasn't happened yet.
