We have been hearing the announcement from Microsoft right from  
PDC2000 that they have realsed new languages viz. C#, VB.NET and  
JScript.NET  
This artice of mine is going to introduce to u JScript.NET  
Jscript's association with the ECMAScript standard has helped its  
success considerably, this has led to a close compatibality with  
JavaScript. The most dramatic impact on performance in JScript.NET is  
that it is a true compiled language, which makes it possible to  
achieve performance comparable to that of C# and Visual Basic.NET. As  
JScript is a part of .NET it automatically benefits from all the goodies
.NET offers.

.NET ships with a compiler for JScript.NET called jsc
Jscript can be compiled as a .exe or a .dll (default), Jscript can  
also be used in ASP.NET pages and create web services by specifying  
"Language=JScript".  

Creating a Simple .exe using JScript Hello.js
//Copy this line in a file Hello.js  
//Compile it as jsc /exe Hello.js to produce Hello.exe  

print("Hello From Jscript Exe");

  

Creating a Simple Class in Jscript : Class.js
//Copy in a file Class.js  
//Compile it as jsc /exe class.js to produce class.exe  

class Class1  
{  
  function sayHi()  
  {  
   return "Hi from JScript Class";  
  }  
}  
  var o : Class1 = new Class1;  
print(o.sayHi());   


A Bit of OOPS in JScript.NET : class1.js  
//Copy in a file Class1.js  
//Compile it as jsc /exe Class1.js to produce class1.exe  

class Class1  
{  
  function sayHi()  
  {  
   return "Hi from JScript Class";  
  }  
}  


class c2 extends Class1  
{  
  protected var name : String; //variable of type string  

  function get fname() : String //property get (acessor)  
  {  
   return this.name;  
  }  

  function set fname(newName : String) //property let (mutator)  
  {  
   this.name = newName;  
  }  

}  

  var o : c2 = new c2;  
  print(o.sayHi());  
  o.fname = "Manish";  
  print(o.fname);  

  


Creating a Simple WebService in JScript.NET : JSweb.asmx  
<%@ WebService Language ="JScript" Class="MyJS" % >  
import System.Web.Services;
class MyJS extends WebService  
{  
  WebMethodAttribute function sayHi() : String  
  {  
   return "Hi from a JScript.NET web service";  
  }  
}  
  

JScript.NET blends seemlessly in the .NET framwework and so will other  
languages like SmallTalk, FujitsuCOBOL and other .NET compatible  
languages.
