It is generally accepted that a complete specification for a programming language includes a description, possibly idealized, of a machine or processor for that language. In most practical contexts, a programming language involves a computer; consequently, programming languages are usually defined and studied this way. The practical necessity that a programming language support adequate abstractions is expressed by the abstraction principle.

  • As Python and JavaScript have gained popularity, PHP’s popularity has dropped.
  • This comparison analyzes trends in the number of projects hosted by a popular community programming repository.
  • It does not require a translator to convert the programs because computers directly understand the machine language programs.
  • It is a structured imperative programming language, which bases its implementation on stacks.

It is an imperative procedural language that was developed by David May and his colleagues at INMOS. Occam-pi is a variant of Occam that has been extended to include nested protocols, recursion, protocol inheritance, array constructors and run-time process creation. It provides the programmers with abilities to write an ALGOL-like code that can be run on small machines. It is a purely functional, not-Turing-complete language, which means that all its programs are guaranteed to terminate. Charity was designed at the University of Calgary, a public University in Canada. Sruthi is a content writer for Simplilearn, with brief prior experience in marketing, journalistic reporting, photography, editing, designing, video-making, and event management.

Type System

There are many uses for PHP, although mostly for website development. You can use it to manage dynamic content and databases on a website, for example. The latter is particularly relevant, as it integrates well with database languages such as MySQL. As mentioned, JavaScript is a language used to write code that runs in web browsers. As such, it has a wide range of applications and is especially useful for making web pages interactive and responsive.

Limbo is used for applications running on Inferno operating system. Alex that was initially a part of the Plan 9 operating system is the predecessor of Limbo. Hypertext Markup Language, abbreviated as HTML, is the most prominent markup language that is used for web pages. It is written in the form of HTML tags that are surrounded by angular brackets. HTML tags describe the appearance of the text in a document and can be embedded into certain other code to affect the web browser behavior. Standardized General Markup Language has descended from IBM’s Generalized Markup Language.

How To Learn Javascript

Object REXX is an object-oriented scripting language that is based on REXX. It is a structured imperative programming language, which bases its implementation on stacks. It supports an interactive execution of commands as well as the compilation of sequences of commands. Many web developers find it essential to learn PHP, as this language is used to build more than 80% of websites on the Internet, including notable sites like Facebook and Yahoo.

It is an ISO standard metalanguage that can define markup languages for documents. It was designed with the intent of sharing machine-readable documents of large projects that had to be retained for long years. Abbreviated as MEL, it is a scripting language that is used to support tasks on the Maya software. It is an event-driven scripting language that provides the programmers with an extensive API. It is a java scripting language that is syntactically similar to Java and runs on the Java Runtime Environment along with scripting commands and syntax.

Multiparadigm languages allow a program to use multiple programming styles to work at once in a single program and combine constructs from different programming languages. Constraint programming languages fall under declarative programming language and express relationships between their variables as constraints. Interpreted languages enable programs to be executed from source code with the help of an interpreter, rather than being compiled. Examples include Apache Ant, JavaScript, PostScript and Windows PowerShell. In this article, we explore a list of 50 programming languages and explain how they work.
