    JScript is Microsoft's version of Javascript. JScript isn't supported on browsers other than Internet Explorer.

    I don't think it's really much different - the basics are the same as EMCAScript (or whatever the official JavaScript is called), it's just that it encompasses ActiveX and such. Basically just MS's implementation of JavaScript, but you're right - try to learn it the cross-browser way.

    Also, I'm fairly certain MS products don't differentiate between Javascript or JScript - they all get ran by the JScript ActiveX scripting engine, which is used by IE, ASP, WSH, etc.

    JScript.Net is probably something new, though.

    1. Java is completely different than Javascript (both share syntax based on the C language). Netscape invented Javascript, originally called it LiveScript, but changed the name as Java became popular.

    2. Microsoft released JScript for IE to compete with Netscape's Javascript, with pretty much the same thing, except with MS's extensions to it for IE.

    3. Javascript has been standardized as ECMAScript, by the ECMA (European Computer Manufacturer's Association).

    4. JScript and Javascript (still controlled by Netscape) claim compatibility with the standardized ECMAScript.

    4. That said, IE will treat Javascript code as JScript to run it.
