JScript is Microsoft's dialect of the ECMAScript standard that is used in Microsoft's Internet Explorer. JScript is implemented as an Active Scripting engine, so it can be "plugged in" to OLE Automation applications that support Active Scripting, such as Internet Explorer, Active Server Pages, and Windows Script Host. It also means such applications can use multiple Active Scripting languages, e.g., JScript, VBScript or PerlScript.
