Prototype-based Objects

Since JScript is an object-oriented programming language, it supports the definition of custom constructor functions and inheritance. Constructor functions (also called constructors) provide the ability to design and implement your own prototype-based objects. Inheritance allows prototype-based objects to share a common set of properties and methods that can be dynamically added or removed.

In many cases, the class-based objects should be used instead of prototype-based objects. Class-based objects can be passed to methods written in other .NET Framework languages. Furthermore, class-based objects provide type safety and produce efficient code.
