JScript doesn't really have the concept of modules, but you can import other JScript libraries by reading them into global
memory:
var g_fso = new ActiveXObject( "Scripting.FileSystemObject" );
var g_ts = g_fso.OpenTextFile( "MyJSFunctions.js" );
var g_lib = g_ts.ReadAll();
g_ts.Close();
eval( g_lib );

using System;
using SWF = System.Windows.Forms;
using System.Xml;
...
Console.WriteLine ("foo");
SWF.Form x = new SWF.Form ();
XmlDocument doc = new XmlDocument ();
|
import System
import System.Windows.Forms as SWF
import System.Xml
print "foo"
x = SWF.Form()
doc = XmlDocument()
|
JScript doesn't use namespaces.
|
|
|
|
|
readonly int X = 2;
const int Y = 3;
|
final X = 2
static final Y = 3
|
There are no constants or read-only variables in JScript.
