Comparison Of Multi-paradigm Programming Languages
Programming languages can be grouped by the number and types of paradigms supported. Paradigm summaries A concise reference for the programming paradigms listed in this article. * Concurrent programming – have language constructs for concurrency, these may involve multi-threading, support for distributed computing, message passing, shared resources (including shared memory), or futures ** Actor programming – concurrent computation with ''actors'' that make local decisions in response to the environment (capable of selfish or competitive behaviour) * Constraint programming – relations between variables are expressed as constraints (or constraint networks), directing allowable solutions (uses constraint satisfaction or simplex algorithm) * Dataflow programming – forced recalculation of formulas when data values change (e.g. spreadsheets) * Declarative programming – describes what computation should perform, without specifying detailed state changes cf. imperative pro ...

Programming Language
A programming language is a system of notation for writing computer programs. Programming languages are described in terms of their Syntax (programming languages), syntax (form) and semantics (computer science), semantics (meaning), usually defined by a formal language. Languages usually provide features such as a type system, Variable (computer science), variables, and mechanisms for Exception handling (programming), error handling. An Programming language implementation, implementation of a programming language is required in order to Execution (computing), execute programs, namely an Interpreter (computing), interpreter or a compiler. An interpreter directly executes the source code, while a compiler produces an executable program. Computer architecture has strongly influenced the design of programming languages, with the most common type (imperative languages—which implement operations in a specified order) developed to perform well on the popular von Neumann architecture. ...

Reflective Programming
In computer science, reflective programming or reflection is the ability of a process to examine, introspect, and modify its own structure and behavior. Historical background The earliest computers were programmed in their native assembly languages, which were inherently reflective, as these original architectures could be programmed by defining instructions as data and using self-modifying code. As the bulk of programming moved to higher-level compiled languages such as ALGOL, COBOL, Fortran, Pascal, and C, this reflective ability largely disappeared until new programming languages with reflection built into their type systems appeared. Brian Cantwell Smith's 1982 doctoral dissertation introduced the notion of computational reflection in procedural programming languages and the notion of the meta-circular interpreter as a component of 3-Lisp. Uses Reflection helps programmers make generic software libraries to display data, process different formats of data, perform ...

BETA (programming Language)
BETA is a pure object-oriented language originating within the "Scandinavian School" in object-orientation where the first object-oriented language Simula was developed.SourceOle Lehrmann Madsen: An overview of BETA Among its notable features, it introduced nested classes, and unified classes with procedures into so called patterns. It has been in development since 1976, with implementations known since 1986, by Kristen Nygaard together with Bent Bruun Kristensen, Ole Lehrmann Madsen, and Birger Møller-Pedersen, at the University of Oslo. The project is inactive as of October 2020. Features Technical overview From a technical perspective, BETA provides several unique features. Classes and Procedures are unified to one concept, a Pattern. Also, classes are defined as properties/attributes of objects. This means that a class cannot be instantiated without an explicit object context. A consequence of this is that BETA supports nested classes. Classes can be virtually defined, ...

APL (programming Language)
APL (named after the book ''A Programming Language'') is a programming language developed in the 1960s by Kenneth E. Iverson. Its central datatype is the multidimensional array. It uses a large range of special graphic symbols to represent most functions and operators, leading to very concise code. It has been an important influence on the development of concept modeling, spreadsheets, functional programming, and computer math packages. It has also inspired several other programming languages. History Mathematical notation A mathematical notation for manipulating arrays was developed by Kenneth E. Iverson, starting in 1957 at Harvard University. In 1960, he began work for IBM where he developed this notation with Adin Falkoff and published it in his book ''A Programming Language'' in 1962. The preface states its premise: This notation was used inside IBM for short research reports on computer systems, such as the Burroughs B5000 and its stack mechanism when stack m ...

AmigaE
Amiga E is a programming language created by Wouter van Oortmerssen on the Amiga computer. The work on the language started in 1991 and was first released in 1993. The original incarnation of Amiga E was being developed until 1997, when the popularity of the Amiga platform dropped significantly after the bankruptcy of Amiga intellectual property owner Escom AG. According to Wouter van Oortmerssen:"It is a general-purpose programming language, and the Amiga implementation is specifically targeted at programming system applications. ..ref name=":0">"In his own words:"Amiga E was a tremendous success, it became one of the most popular programming languages on the Amiga." Overview Amiga E combines features from several languages but follows the original C programming language most closely in terms of basic concepts. Amiga E's main benefits are fast compilation (allowing it to be used in place of a scripting language), very readable source code, flexible type system, powerful mo ...
