JavaScript is a compact, cross-platform, object-based scripting language that extends the capabilities of HTML. JavaScript is integrated with HTML to allow developers to create interactive Web pages. For example, you can create a JavaScript program to prevalidate a form before sending it back to the server, set options based on user preferences, update text displayed in a form’s text box, etc. Because JavaScript is downloaded with the HTML page, its execution requires no further interaction with the server.

JavaScript is easy to learn, yet powerful enough for sophisticated scripting tasks. It uses syntax similar to C and C++ and has object-oriented features that use prototype-based inheritance.

M-Business JavaScript engine is the iAnywhere Solutions, Inc. implementation of client-side JavaScript. Many JavaScript features that are not considered high priority for handheld devices are not supported to conserve mobile device resources. At the same time, most of the features of PODS are directly available to JavaScript Engine as if they were provided by JavaScript native objects. For details on what JavaScript Engine omits from JavaScript and what it adds from PODS, see M-Business JavaScript Engine reference.
