Whoa, whoa. One thing at a time. Okay, for all practical reasons, you should not code in anything but javascript. Everything that Microsoft uses (JScript, VBScript (not counting ASP), etc.) is ActiveX and is INSECURE by microsoft’s own admission. They are also limited to Internet Explorer and won’t work with other browsers.
Javascript is not a microsoft product, does not rely on IE, and completely compatible. It is one of the cornerstones of AJAX (AJAX stands for asynchronous javascript and xml).
As for “best viewed with IE”, if it can’t be viewed in firefox, chances are there’s no need to view it. The only thing that firefox doesn’t support that IE does is activeX, and if Microsoft admits its insecure, I don’t want to be near it.
JScript is Microsoft’s implementation of ECMAScript. JScript runs under Internet Explorer.
Javascript is a common computer programming language developed by ECMA for use in web applications primarily on the client.
Microsoft has implemented Netscape’s original JavaScript specification to create a scripting language called JScript, which is the default scripting language interpreted in Internet Explorer. Like Netscape’s JavaScript implementation, JScript supports the full specification of ECMAScript.
What is different is the Document Object Model (DOM) bound with JScript. While all browsers have their own implementation of DOM Level 0 (vendor-specific), Internet Explorer implemented only some of the W3C recommended DOM Levels (1, 2 and 3).
