This is just filler text so you can see what the page looks like full of text. JScript is an interpreted, object-based scripting language. Although it has fewer capabilities than full-fledged object-oriented languages like C++ and Java, JScript is more than sufficiently powerful for its intended purposes. JScript is not a cut-down version of any other language (it is only distantly and indirectly related to Java, for example), and it is not a simplification of anything. It is, however, limited. You cannot write standalone applications in it, for example, and it has little capability for reading or writing files. Moreover, JScript scripts can run only in the presence of an interpreter, either in a Web server or a Web browser. JScript is a loosely typed language. That means you do not have to declare the data types of variables explicitly. In fact, you cannot explicitly declare data types in JScript. Moreover, in many cases JScript performs conversions automatically when they are needed. For instance, if you try to add a number to an item that consists of text (a string), the number is converted to text. The rest of this tutorial is an overview of JScript features. For full details of the language implementation, consult the language reference. |
