JScript provides 13 primitive data types and 13 reference data types. In addition to these, you can declare new data types or use any of the Common Language Specification (CLS)-compliant .NET Framework data types. This section includes information about the intrinsic data types, how to extend those types, how to define your own data types, how to enter data, and how to convert data from one type to another.
