Information About

Jscript




JavaScript (the Netscape / Mozilla implementation of the ECMA specification), JScript, and ECMAScript are very similar languages. In fact the name "JavaScript" is often used to refer to ECMAScript or JScript.

JavaScript is used on web pages for scripting, although it can be and is also used in other embedding scenarios.

: ''For general information about the language, its history, and uses see the JavaScript article. The article on ECMAScript has information on various dialects and implementations of ECMAScript and the history of the specification. JavaScript Syntax is described in its own article. The rest of this article focuses on Microsoft implementation.''

JScript is implemented as a Windows Script engine. This means that it can be "plugged in" to any application that supports Windows Script, such as Internet Explorer, Active Server Pages, and Windows Script Host. It also means that any application supporting Windows Script can use multiple languages — JScript, VBScript , Perl , and others. JScript was first supported in Internet Explorer browser 3.0 released in August 1996 . As with any other Active Scripting engine, it is available through Internet Explorer, Windows Script Host , and Active Server Pages . The typical File Extension of JScript Source Code files is .js.

The most recent version of JScript is JScript .NET , which is based on the yet-unfinished edition 4 of the ECMAScript standard, and can be compiled for the Microsoft .NET platform. JScript.NET adds several new features to ECMAScript ed. 3, such as optional static type annotations.


VERSIONS



JScript

The original JScript is an Active Scripting engine. Like other Active Scripting languages, it is built on the COM/OLE Automation platform and provides scripting capabilities to host applications.
This is the version used when hosting JScript inside a Web page displayed by Internet Explorer , in an HTML Application , in Classic ASP , in Windows Script Host scripts and several other Automation environments.
JScript is sometimes referred to as "classic JScript" or "Active Scripting JScript" to differentiate it from newer .NET-based versions.
