Programming language

A programming language is an artificial language for expressing computer programs.[1]

Programming languages typically allow software to be written in a human readable manner.

Execution of a program requires an implementation. There are two main approaches for implementing a programming language – compilation, where programs are compiled ahead-of-time to machine code, and interpretation, where programs are directly executed. In addition to these two extremes, some implementations use hybrid approaches such as just-in-time compilation and bytecode interpreters.[2]

The design of programming languages has been strongly influenced by computer architecture, with most imperative languages designed around the ubiquitous von Neumann architecture.[3] While early programming languages were closely tied to the hardware, modern languages often hide hardware details via abstraction in an effort to enable better software with less effort.
