Object-based language

The term "object-based language" may be used in a technical sense to describe any programming language that uses the idea of encapsulating state and operations inside "objects". Object-based languages need not support inheritance or subtyping, but those that do are also said to be "object-oriented". Object-based languages that do not support inheritance or subtyping are usually not considered to be true object-oriented languages.

Examples of object-oriented languages, in rough chronological order, include Simula, Smalltalk, C++ (whose object model was based on Simula's), Objective-C (whose object model was based on Smalltalk's), Eiffel, Xojo (previously REALbasic), Python, Ruby, Java, Visual Basic .NET, C#, and Fortran 2003. Examples of a language that is object-based, but not object-oriented are early versions of Ada, Visual Basic (VB), and Fortran 90. These languages all support the definition of an object as a data structure, but lack polymorphism and inheritance.

In practice, the term "object-based" is usually applied to those object-based languages that are not also object-oriented, although all object-oriented languages are also object-based, by definition. Instead, the terms "object-based" and "object-oriented" are normally used as mutually exclusive alternatives, rather than as categories that overlap.
