Advantages of JavaScript

Up to this point, you may not have seen any big reasons where and why JavaScript can help you. It is object based, can be interpreted within a browser, and there are security measures in place—but so is Java. Now that browsers support plug-ins and ActiveX controls, it is possible to design client-side functionality with more common languages like C++ or Visual Basic. So what does JavaScript really give you?

For starters, it is platform independent. This is a major advantage over ActiveX controls and plug-ins because they have to be recompiled and potentially rewritten for the various platforms out there today. Netscape Navigator, for example, runs on nearly 20 platforms and even though most of these are various flavors of UNIX, at its core, you would still have to build a control or plug-in for Windows 16- and 32-bit systems, MacOS, UNIX, and OS/2. Also note that flavors of UNIX can run on several types of processors (MIPS, Intel, and so on), and Windows NT runs on Intel and Alpha machines. This becomes quite an extensive list of components to maintain if you develop in a platform-dependant language.
