JScript 5.5 Features

JScript includes the following features:

Widely supported. If your application needs to run on any Internet platform, anywhere, JScript is the scripting language of choice.
Loosely typed. There are no explicit data types in JScript and in many cases JScript performs conversions automatically. For example, if you add a number to an item consisting of text (a string), the number is converted to text.
Evaluate code at run time. You can redefine your program dynamically, giving scripts greater flexibility, especially on DHTML pages.
Prototype-based object orientation provides the benefits of an object-oriented language without statically defined classes.
Support for regular expressions.
Error handling, using the try-throw-catch exception handler.
Effective with Windows CE .NET version 4.2, JScript can support script authoring, although implementation is optional and not all platforms include this feature. For more information, see the manufacturer's SDK documentation.

**Note **Windows CE .NET does not provide type libraries for script interfaces, and script debugging is not supported.

A complete description of both ECMA and non-ECMA features of JScript 5.5 is available at this Microsoft Web site.
