WebScript Programmer's Quick Reference to Foundation Classes

As you learned in the previous chapter, when you write an application in WebScript, all values are objects, even simple values such as numbers or strings. The objects that represent strings, numbers, arrays, dictionaries, and other basic constructs are defined by classes in the Foundation framework. You use classes from the Foundation framework in virtually all WebScript applications.

This chapter gives you an overview of the Foundation framework classes most commonly used in WebScript. More detailed descriptions are provided by the class specifications in the Foundation Framework Reference. However, not all methods in these class specifications are available in WebScript. For example, some classes define methods that take structures as arguments or return structures, but because structures are not supported in WebScript, you cannot use these methods. For more information, see "WebScript for Objective-C Developers" in the previous chapter.
