Study Notes
Programming Languages: A Brief Overview
-
Programming languages are systems of notation for writing computer programs.
-
Programming languages are usually split into syntax (form) and semantics (meaning).
-
Some languages are defined by a specification document while others have a dominant implementation that is treated as a reference.
-
Programming language theory studies the design, implementation, analysis, characterization, and classification of programming languages.
-
Programming languages differ from natural languages in that they allow humans to communicate instructions to machines.
-
Programming languages usually contain abstractions for defining and manipulating data structures or controlling the flow of execution.
-
Early computers were programmed without the help of a stored program, by modifying their circuitry or setting banks of physical controls.
-
High-level programming languages were developed in the 1950s.
-
The period from the 1960s to the late 1970s brought the development of the major language paradigms now in use.
-
The 1980s were years of relative consolidation, and the functional languages community moved to standardize ML and Lisp.
-
Programming language evolution continues, in both industry and research.
-
Programming languages have syntax and semantics, and their semantics define how and when program constructs should produce a program behavior.Overview of Programming Languages
-
Programming languages are used to write computer programs and have syntactic form separate from their semantics.
-
A type system defines how a programming language classifies values and expressions into types, and how they interact.
-
Typed languages define types of data to which an operation is applicable; untyped languages allow any operation to be performed on any data.
-
Static typing determines types prior to execution, while dynamic typing determines type-safety at runtime.
-
Weak typing allows a value of one type to be treated as another, while strong typing prevents program faults.
-
A language's core library is conventionally made available by all implementations of the language.
-
Programming languages have been designed from scratch, altered to meet new needs, and combined with other languages.
-
A programming language specification is an artifact that the language users and the implementors can use to agree upon whether a piece of source code is a valid program in that language.
-
An implementation of a programming language provides a way to write programs in that language and execute them on one or more configurations of hardware and software.
-
Proprietary programming languages are commonly domain-specific languages or internal scripting languages for a single product.
-
A programming language provides a structured mechanism for defining pieces of data and operations on that data.
-
Determining which is the most widely used programming language is difficult, and various methods of measuring language popularity have been proposed.Overview of Programming Languages
-
Programming languages can be divided into dialects, flavors, and implementations that don't change the intrinsic nature of the language.
-
There is no overarching classification scheme for programming languages, and a given programming language usually has multiple predecessor languages.
-
Languages can be classified by programming paradigm and intended domain of use, with general-purpose programming languages distinguished from domain-specific programming languages.
-
Programming paradigms include imperative programming, declarative programming, procedural programming, object-oriented programming, functional programming, and logic programming.
-
Programming languages can also be classified by their purpose, such as general-purpose, system programming languages, scripting languages, domain-specific languages, or concurrent/distributed languages.
-
Some general-purpose languages were designed largely with educational goals.
-
A programming language may also be classified by factors unrelated to the programming paradigm, such as whether it uses English language keywords or is deliberately esoteric.
-
Lisp dialects are considered to be those languages that use basic S-expression syntax and Lisp-like semantics.
-
It can be difficult for an inexperienced programmer to find the right documentation for a programming language with several dialects.
-
Java is both an object-oriented and concurrent language, while Python is an object-oriented scripting language.
-
A dialect of a programming language or a data exchange language is a variation or extension of the language that does not change its intrinsic nature.
-
Implementors may deviate from the standard to make a new dialect if they consider the standards insufficient, inadequate, or illegitimate.
