Questions tagged [programming-languages]

A programming language is an artificial language designed to express computations that can be performed by a machine. **Please note:** As is the case elsewhere on Stack Overflow, resource and tutorial recommendation requests, requests for lists of things ("which languages have this feature..."), and excessively opinion-based ("what's the best...") questions are off topic.

In the 1950s E. Dykstra stated that:

We can call something a programming language if it does three things: execute sequential statements, make decisions and allow looping or iteration.

A programming language is an artificial language designed to express computations that can be performed by a machine, particularly a computer.

This tag is particularly suitable for questions about programming languages and programming language design in general.

A programming language is a notation for writing programs, which are specifications of a computation or algorithm.

A popular weblog dedicated to programming languages design is Lambda the Ultimate.
