A language that also supports [inheritance](/source/Inheritance_(object-oriented_programming)) or [subtyping](/source/Subtyping) is classified as [object-oriented](/source/Object-oriented_programming).[1] Even though object-oriented programming is a superset of object-based programming, some authors distinguish them by name only when it is useful to point that a given programming language lacks inheritance.[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*] Examples of strictly object-based languages – supporting an object feature but not inheritance or subtyping – are early versions of [Ada](/source/Ada_(programming_language)),[2] [CLU](/source/CLU_(programming_language)), [Visual Basic 6](/source/Visual_Basic_6) (VB6), and [Fortran 90](/source/Fortran_90). Some classify [prototype-based programming](/source/Prototype-based_programming) as object-based even though it supports inheritance and subtyping albeit not via a [class](/source/Class_(programming)) concept. Instead an object inherits its state and behavior from a *template* object. A commonly used language with prototype-based programming support is [JavaScript](/source/JavaScript). ## See also - [Class (programming)](/source/Class_(programming)) - [Class-based programming](/source/Class-based_programming) - [Object (computer science)](/source/Object_(computer_science)) - [Object-oriented programming](/source/Object-oriented_programming) ## References 1. **[^](#cite_ref-1)** Wegner, Peter (December 1987).

Retrieved 15 December 2013. Ada 83 itself is generally not considered to be object-oriented; rather, according to the terminology of Wegner [Weg 87], it is said to be object-based, since it provides only a restricted form of inheritance and it lacks polymorphism. v t e Programming paradigms Imperative Structured Jackson structures Block-structured Modular Non-structured Procedural Programming in the large and in the small Design by contract Invariant-based Nested function Object-oriented Class-based, Prototype-based, Object-based Agent Immutable object Persistent Uniform function call syntax Declarative Functional Recursive Anonymous function (Partial application) Higher-order Purely functional Total Strict GADTs Dependent types Functional logic Point-free style Expression-oriented Applicative, Concatenative Function-level, Value-level Monad Dataflow Flow-based Reactive (Functional reactive) Signals Streams Synchronous Logic Abductive logic Answer set Constraint (Constraint logic) Inductive logic Nondeterministic Ontology Probabilistic logic Query Domain- specific language (DSL) Algebraic modeling Array Automata-based (Action) Command (Spacecraft) Differentiable End-user Grammar-oriented Interface description Language-oriented List comprehension Low-code Modeling Natural language Non-English-based Page description Pipes and filters Probabilistic Quantum Scientific Scripting Set-theoretic Simulation Stack-based System Tactile Templating Transformation (Graph rewriting, Production, Pattern) Visual Concurrent, parallel Actor-based Automatic mutual exclusion Choreographic programming Concurrent logic (Concurrent constraint logic) Concurrent OO Macroprogramming Multitier programming Organic computing Parallel programming models Partitioned global address space Process-oriented Relativistic programming Service-oriented Structured concurrency Metaprogramming Attribute-oriented Automatic (Inductive) Dynamic Extensible Generic Homoiconicity Interactive Macro (Hygienic) Metalinguistic abstraction Multi-stage Program synthesis (Bayesian, by demonstration, by example, vibe coding) Reflective Self-modifying code Symbolic Template Separation of concerns Aspects Components Data-driven Data-oriented Event-driven Features Literate Roles Subjects Comparisons/Lists Comparison (multi-paradigm, object-oriented, functional), List (OO, by type) v t e Types of programming languages Level Machine Assembly Compiled Interpreted Low-level High-level Very high-level Esoteric Generation First Second Third Fourth Fifth Authority control databases International GND FAST National United States Czech Republic Israel Other Yale LUX This programming-language-related article is a stub.
