List Of Programming Languages By Type
Array languages[edit]
Main category: Array programming languages
Array programming (also termed vector or multidimensional) languages generalize operations on scalars to apply transparently to vectors, matrices, and higher-dimensional arrays.
Assembly languages[edit]
Main article: Assembly language
Assembly languages directly correspond to a machine language (see below), although there may not be a 1-1 mapping between an individual statement and an individual instruction, so machine code instructions appear in a form understandable by humans. Assembly languages let programmers use symbolic addresses, which the assembler converts to absolute or relocatable addresses. Most assemblers also support macros and symbolic constants.
Authoring languages[edit]
Main article: Authoring language
An authoring language is a programming language desined for use by a non-computer expert to easily create tutorials, websites, and other interactive computer programs.
Constraint programming languages[edit]
Main article: Constraint programming
A constraint programming language is a declarative programming language where relationships between variables are expressed as constraints. Execution proceeds by attempting to find values for the variables which satisfy all declared constraints.
Command line interface languages[edit]
Command-line interface (CLI) languages are also called batch languages or job control languages. Examples:
bash (the Bourne-Again shell from GNU, Free Software Foundation (FSF))
DIGITAL Command Language (DCL) – standard CLI language for VMS (DEC, Compaq, HP)
DOS batch language(standard CLI/batch language for the IBM PCrunning DOS operating systems, popular before Windows)
Hamilton C shell (a C shell for Windows)
ksh (a standard Unix shell, written by David Korn)
sh (the standard Unix shell, written by Stephen R. Bourne)
TACL (Tandem Advanced Command Language)
Windows batch language(Windows batch file language as understood by COMMAND.COM and CMD.EXE)

Concurrent languages[edit]
Main category: Concurrent programming languagesFor a more comprehensive list, see List of concurrent and parallel programming languages.
Message passing languages provide language constructs for concurrency. The predominant paradigm for concurrency in mainstream languages such as Java is shared memory concurrency. Concurrent languages that make use of message passing have generally been inspired by process calculi such as communicating sequential processes (CSP) or the π-calculus.
Ada – multi-purpose language
Alef – concurrent language with threads and message passing, used for systems programming in early versions of Plan 9 from Bell Labs
Ateji PX an extension of the Java language for parallelism
Ballerina - a language designed for implementing and orchestrating micro-services. Provides a message based parallel-first concurrency model.
ChucK – domain specific programming language for audio, precise control over concurrency and timing
Cω – C Omega, a research language extending C#, uses asynchronous communication
Clojure – a dialect of Lisp for the Java virtual machine
Concurrent Pascal (by Brinch-Hansen)
E – uses promises, ensures deadlocks cannot occur
Elixir (runs on the Erlang VM)
Emerald - uses threads and monitors
Erlang – uses asynchronous message passing with nothing shared
Gambit Scheme - using the Termite library
Haskell — supports concurrent, distributed, and parallel programming across multiple machines
Joule – dataflow language, communicates by message passing
Limbo – relative of Alef, used for systems programming in Inferno (operating system)
occam – influenced heavily by Communicating Sequential Processes (CSP)
occam-π – a modern variant of occam, which incorporates ideas from Milner's π-calculus
Oz – multiparadigm language, supports shared-state and message-passing concurrency, and futures, and Mozart Programming System cross-platform Oz
Pict – essentially an executable implementation of Milner's π-calculus
SequenceL – purely functional, automatically parallelizing and race-free
SR – research language
XProc – XML processing language, enabling concurrency
Curly-bracket languages[edit]
Curly-bracket or curly-brace programming languages have a syntax that defines statement blocks using the curly bracket or brace characters { and }. This syntax originated with BCPL (1966), and was popularized by C. Many curly-bracket languages descend from or are strongly influenced by C. Examples of curly-bracket languages include:
ChucK – audio programming language
Cilk – concurrent C for multithreaded parallel programming
Cyclone – a safer C variant
DASL – based on Java
Nemerle – combines C# and ML features, provides syntax extension abilities
Scala (curly-braces optional)
Dataflow languages[edit]
Dataflow programming languages rely on a (usually visual) representation of the flow of data to specify the program. Frequently used for reacting to discrete events or for processing streams of data. Examples of dataflow languages include:
G (used in LabVIEW)
Data-oriented languages[edit]
Data-oriented languages provide powerful ways of searching and manipulating the relations that have been described as entity relationship tables which map one set of things into other sets.[citation needed] Examples of data-oriented languages include:
dBase a relational database access language
MUMPS (an ANSI standard general purpose language with specializations for database work)
Caché (similar to MUMPS)
Tutorial D – see also The Third Manifesto
Visual FoxPro – a native RDBMS engine, object-oriented, RAD
Decision table languages[edit]
Decision tables can be used as an aid to clarifying the logic before writing a program in any language, but in the 1960s a number of languages were developed where the main logic is expressed directly in the form of a decision table, including:
Declarative languages[edit]
Main category: Declarative programming languages
Declarative languages express the logic of a computation without describing its control flow in detail. Declarative programming stands in contrast to imperative programming via imperative programming languages, where control flow is specified by serial orders (imperatives). (Pure) functional and logic-based programming languages are also declarative, and constitute the major subcategories of the declarative category. This section lists additional examples not in those subcategories.
Ant (combine declarative programming and imperative programming)
Distributed Application Specification Language (DASL) (combine declarative programming and imperative programming)
SequenceL – purely functional, automatically parallelizing and race-free
SQL (Only DQL, not DDL, DCL, and DML)
Embeddable languages[edit]
In source code[edit]
Source embeddable languages embed small pieces of executable code inside a piece of free-form text, often a web page.
Client-side embedded languages are limited by the abilities of the browser or intended client. They aim to provide dynamism to web pages without the need to recontact the server.
Server-side embedded languages are much more flexible, since almost any language can be built into a server. The aim of having fragments of server-side code embedded in a web page is to generate additional markup dynamically; the code itself disappears when the page is served, to be replaced by its output.
Server side[edit]
SMX – dedicated to web pages
Tcl – server-side in NaviServer and an essential component in electronics industry systems
WebDNA – dedicated to database-driven websites
The above examples are particularly dedicated to this purpose. A large number of other languages, such as Erlang, Scala, Perl and Ruby can be adapted (for instance, by being made into Apache modules).
Client side[edit]
VBScript (Windows only)
In object code[edit]
A wide variety of dynamic or scripting languages can be embedded in compiled executable code. Basically, object code for the language's interpreter needs to be linked into the executable. Source code fragments for the embedded language can then be passed to an evaluation function as strings. Application control languages can be implemented this way, if the source code is input by the user. Languages with small interpreters are preferred.
Educational Programming languages[edit]
For a more comprehensive list, see List of educational programming languages.
Languages developed primarily for the purpose of teaching and learning of programming.
Esoteric languages[edit]
Main category: Esoteric programming languages
An esoteric programming language is a programming language designed as a test of the boundaries of computer programming language design, as a proof of concept, or as a joke.
Extension languages[edit]
Extension programming languages are languages embedded into another program and used to harness its features in extension scripts.
C/AL (C/SIDE)
JavaScript and some dialects, e.g., JScript
Lua (embedded in many games)
OpenCL (extension of C and C++ to use the GPU and parallel extensions of the CPU)
OptimJ (extension of Java with language support for writing optimization models and powerful abstractions for bulk data processing)
Python (embedded in Maya, Blender, and other 3-D animation packages)
Ruby (Google SketchUp)
Vim script (vim)
Fourth-generation languages[edit]

Functional languages[edit]
Main category: Functional languages
Functional programming languages define programs and subroutines as mathematical functions and treat them as first-class. Many so-called functional languages are "impure", containing imperative features. Many functional languages are tied to mathematical calculation tools. Functional languages include:
Pure[edit]
Coq (Gallina)
Impure[edit]
Standard ML (SML)
Hardware description languages[edit]
For a more comprehensive list, see List of hardware description languages.
In electronics, a hardware description language (HDL) is a specialized computer language used to describe the structure, design, and operation of electronic circuits, and most commonly, digital logic circuits. The two most widely used and well-supported HDL varieties used in industry are Verilog and VHDL. Hardware description languages include:
HDLs for analog circuit design[edit]
Verilog-AMS (Verilog for Analog and Mixed-Signal)
VHDL-AMS (VHDL with Analog/Mixed-Signal extension)
HDLs for digital circuit design[edit]
VHDL (VHSIC HDL)
Imperative languages[edit]
Imperative programming languages may be multi-paradigm and appear in other classifications. Here is a list of programming languages that follow the imperative paradigm:
Interactive mode languages[edit]
Interactive mode languages act as a kind of shell: expressions or statements can be entered one at a time, and the result of their evaluation is seen immediately. The interactive mode is also termed a read–eval–print loop (REPL).
BASIC (some dialects)
Dart (with Observatory or Dartium's developer tools)
Elixir (with iex)
Haskell (with the GHCi or Hugs interpreter)

Interpreted languages[edit]
Interpreted languages are programming languages in which programs may be executed from source code form, by an interpreter. Theoretically, any language can be compiled or interpreted, so the term interpreted language generally refers to languages that are usually interpreted rather than compiled.
AutoHotkey scripting language
AutoIt scripting language
BASIC (some dialects)
Programming Language for Business (PL/B, formerly DATABUS, later versions added optional compiling)
Eiffel (via Melting Ice Technology in EiffelStudio)

List-based languages – LISPs[edit]
List-based languages are a type of data-structured language that are based on the list data structure.
Little languages[edit]
Little languages[4] serve a specialized problem domain.
awk – used for text file manipulation.
Comet – used to solve complex combinatorial optimization problems in areas such as resource allocation and scheduling
sed – parses and transforms text
SQL – has only a few keywords and not all the constructs needed for a full programming language[a] – many database management systems extend SQL with additional constructs as a stored procedure language
Logic-based languages[edit]
Main category: Logic programming languages
Logic-based languages specify a set of attributes that a solution must-have, rather than a set of steps to obtain a solution.
Notable languages following this programming paradigm include:
Flix (a functional programming language with first-class Datalog constraints)
λProlog (a logic programming language featuring polymorphic typing, modular programming, and higher-order programming)
Oz, and Mozart Programming System cross-platform Oz
Prolog (formulates data and the program evaluation mechanism as a special form of mathematical logic called Horn logic and a general proving mechanism called logical resolution)
Mercury (based on Prolog)
Visual Prolog (object-oriented Prolog extension)
Machine languages[edit]
Machine languages are directly executable by a computer's CPU. They are typically formulated as bit patterns, usually represented in octal or hexadecimal. Each bit pattern causes the circuits in the CPU to execute one of the fundamental operations of the hardware. The activation of specific electrical inputs (e.g., CPU package pins for microprocessors), and logical settings for CPU state values, control the processor's computation. Individual machine languages are specific to a family of processors; machine-language code for one family of processors cannot run directly on processors in another family unless the processors in question have additional hardware to support it (for example, DEC VAX processors included a PDP-11 compatibility mode). They are (essentially) always defined by the CPU developer, not by 3rd parties. The symbolic version, the processor's assembly language, is also defined by the developer, in most cases. Some commonly used machine code instruction sets are:
Original 32-bit
16-bit Thumb instructions (subset or registers used)
64-bit (major architecture change, more registers)
Intel 8008, 8080 and 8085
x86:
16-bit x86, first used in the Intel 8086
Intel 8086 and 8088 (the latter was used in the first and early IBM PC)
Intel 80286 (the first x86 processor with protected mode, used in the IBM AT)
Motorola 68000 family (CPUs used in early Apple Macintosh and early Sun computers)
6510 (CPU for Commodore 64)
Western Design Center 65816/65802 (CPU for Apple IIGS and (variant) Super Nintendo Entertainment System)
POWER, first used in the IBM RS/6000
PowerPC – used in Power Macintosh and in many game consoles, particularly of the seventh generation.
Sun Microsystems (Now Oracle) SPARC
Macro languages[edit]
Main category: Macro programming languages
Textual substitution macro languages[edit]
Macro languages transform one source code file into another. A "macro" is essentially a short piece of text that expands into a longer one (not to be confused with hygienic macros), possibly with parameter substitution. They are often used to preprocess source code. Preprocessors can also supply facilities like file inclusion.
Macro languages may be restricted to acting on specially labeled code regions (pre-fixed with a # in the case of the C preprocessor). Alternatively, they may not, but in this case it is still often undesirable to (for instance) expand a macro embedded in a string literal, so they still need a rudimentary awareness of syntax. That being the case, they are often still applicable to more than one language. Contrast with source-embeddable languages like PHP, which are fully featured.
cpp (the C preprocessor)
m4 (originally from AT&T, bundled with Unix)
ML/I (general purpose macro processor)
Application macro languages[edit]
Scripting languages such as Tcl and ECMAScript (ActionScript, ECMAScript for XML, JavaScript, JScript) have been embedded into applications. These are sometimes called "macro languages", although in a somewhat different sense to textual-substitution macros like m4.
Metaprogramming languages[edit]
Metaprogramming is the writing of programs that write or manipulate other programs, including themselves, as their data or that do part of the work that is otherwise done at run time during compile time. In many cases, this allows programmers to get more done in the same amount of time as they would take to write all the code manually.
META II (and META I, a subset)
Multiparadigm languages[edit]
Main article: Comparison of multi-paradigm programming languages
Multiparadigm languages support more than one programming paradigm. They allow a program to use more than one programming style. The goal is to allow programmers to use the best tool for a job, admitting that no one paradigm solves all problems in the easiest or most efficient way.

Numerical analysis[edit]
Several general-purpose programming languages, such as C and Python, are also used for technical computing, this list focuses on languages almost exclusively used for technical computing.
Non-English-based languages[edit]
Main article: Non-English-based programming languages
Object-oriented class-based languages[edit]
Class-based Object-oriented programming languages support objects defined by their class. Class definitions include member data. Message passing is a key concept (if not the key concept) in Object-oriented languages.
Polymorphic functions parameterized by the class of some of their arguments are typically called methods. In languages with single dispatch, classes typically also include method definitions. In languages with multiple dispatch, methods are defined by generic functions. There are exceptions where single dispatch methods are generic functions (e.g. Bigloo's object system).

Actor-Based Concurrent Language (ABCL, ABCL/1, ABCL/R, ABCL/R2, ABCL/c+)
JavaScript (first named Mocha, then LiveScript)
Off-side rule languages[edit]
Main article: Off-side rule § Off-side rule languages
Off-side rule languages denote blocks of code by their indentation.
Procedural languages[edit]
Procedural programming languages are based on the concept of the unit and scope (the data viewing range) of an executable code statement. A procedural program is composed of one or more units or modules, either user coded or provided in a code library; each module is composed of one or more procedures, also called a function, routine, subroutine, or method, depending on the language. Examples of procedural languages include:
Ada (multi-purpose language)
BASIC (these lack most modularity in (especially) versions before about 1990)
C++ (C with objects plus much else, such as, generics through STL)
C# (similar to Java/C++)
ChucK (C/Java-like syntax, with new syntax elements for time and parallelism)
JavaScript (first named Mocha, then LiveScript)

Free Pascal (FPC)
PL/I (large general purpose language, originally for IBM mainframes)
Query languages[edit]
Main article: Query language
Reflective Language[edit]
Reflective languages let programs examine and possibly modify their high level structure at runtime or compile-time. This is most common in high-level virtual machine programming languages like Smalltalk, and less common in lower-level programming languages like C. Languages and platforms supporting reflection:See also: Aspect-oriented programming
Oberon-2 – ETH Oberon System
Smalltalk (pure object-orientation, originally from Xerox PARC)
Rule-based languages[edit]
Rule-based languages instantiate rules when activated by conditions in a set of data. Of all possible activations, some set is selected and the statements belonging to those rules execute. Rule-based languages include:[citation needed]
ToonTalk – robots are rules
Scripting languages[edit]
"Scripting language" has two apparently different, but in fact similar, meanings. In a traditional sense, scripting languages are designed to automate frequently used tasks that usually involve calling or passing commands to external programs. Many complex application programs provide built-in languages that let users automate tasks. Those that are interpretive are often called scripting languages.
Recently, many applications have built-in traditional scripting languages, such as Perl or Visual Basic, but there are quite a few native scripting languages still in use. Many scripting languages are compiled to bytecode and then this (usually) platform-independent bytecode is run through a virtual machine (compare to Java virtual machine).
Ch (Embeddable C/C++ interpreter)
JavaScript (first named Mocha, then LiveScript)
Game Maker Language (GML)
Julia (still, compiled on the fly to machine code)
Object REXX (OREXX, OOREXX)

Many shell command languages such as Unix shell or DIGITAL Command Language (DCL) on VMS have powerful scripting abilities.
Stack-based languages[edit]
Main category: Stack-oriented programming languages
Stack-based languages are a type of data-structured language that are based on the stack data structure.
Synchronous languages[edit]
Main category: Synchronous programming languages
Synchronous programming languages are optimized for programming reactive systems, systems that are often interrupted and must respond quickly. Many such systems are also called realtime systems, and are used often in embedded systems.
Examples:
Shading languages[edit]
See also: Category:Shading languages
A shading language is a graphics programming language adapted to programming shader effects. Such language forms usually consist of special data types, like "color" and "normal". Due to the variety of target markets for 3D computer graphics.
Real-time rendering[edit]
They provide both higher hardware abstraction and a more flexible programming model than previous paradigms which hardcoded transformation and shading equations. This gives the programmer greater control over the rendering process and delivers richer content at lower overhead.
ARB assembly language (ARB assembly)
OpenGL Shading Language (GLSL or glslang)
High-Level Shading Language (HLSL) or DirectX Shader Assembly Language
PlayStation Shader Language (PSSL)

System languages[edit]
The system programming languages are for low level tasks like memory management or task management. A system programming language usually refers to a programming language used for system programming; such languages are designed for writing system software, which usually requires different development approaches when compared with application software.
System software is computer software designed to operate and control the computer hardware, and to provide a platform for running application software. System software includes software categories such as operating systems, utility software, device drivers, compilers, and linkers. Examples of system languages include:
