The resulting.
inconsistencies make it difficult to write JavaScript that behaves the same in both Netscape Navigator and Microsoft Internet Explorer. This could be attributed to the slow.
progress of JavaScript through the standards bodies.
JavaScript runs a lot slower than C, as it is purely interpreted. Netscape and allies say JavaScript is an "open standard" in an effort to keep Microsoft from monopolizing web software as they have desktop software. Netscape and Sun have co-operated to enable Java and JavaScript to exchange messages and data. JavaScript should not be confused with Java, and is a Netscape, not Sun trademark (Reference #1).
VB Script.
Microsoft's Visual Basic Scripting Edition (VBScript), a subset of Visual Basic for Applications, is a powerful language for Internet application development, where it can serve as a scripting language for server-side, client-side, and system scripting. It is much simpler and is similar to JavaScript. VBScript makes it possible to add interactive features like buttons and scrollbars to Web pages. VBScript can be used with Microsoft Office applications and others. This scripting language was developed by Microsoft and works with Internet Explorer.
VB Scripts syntax statements are bounded by end-of-line, and normal Basic keywords are used for control structures and code modularity. VBScript supports a modest set of data types like various numeric types, strings, dates, booleans, arrays, and object references. Variables in VBScript are typed, but the interpreter does not do strong type enforcement. VBScript supports subroutines and functions, and can interact with objects provided by its environment (usually a scriptable application). VBScript does not support the definition of new object classes, nor does it support overloading or polymorphism. .
The language has fairly good support for handling time, dates, and strings. The newest version of VBScript also supports a dictionary object, an associative array for storing string data.
