So called esoteric programming languages (esolangs) are highly experimental and [fun](fun.md) [programming languages](programming_language.md) that employ bizarre ideas. Popular languages of this kind include [brainfuck](brainfuck.md), [chef](chef.md) or [omgrofl](omgrofl.md).
There is a wiki for esolangs, the [Esolang Wiki](https://esolangs.org). If you want to behold esolangs in all their beauty, see [hello world in different languages](https://esolangs.org/wiki/Hello_world_program_in_esoteric_languages_(nonalphabetic_and_A-M).

- **They are actually useful research in language design**, even if most of the ideas aren't useful directly, esolangs really teach us about the borders and definitions of what languages are. And sometimes, by mistake, actual discoveries are made.
- They are **[fun](fun.md)**.
- **They are great exercise in [programming](programming.md)** and design. Simple languages that are allowed to not be useful are potentially good for education as they let the programmer fully focus on a specific idea and its implementation.
- **They blend technology with [art](art.md)**, train creativity.
- **They are a breath of fresh air** in the sometimes too serious area of technology. Hobbyist and non-commercial programming communities are always great to have.
## History
INTERCAL, made in 1972 by Donald Woods and James Lyon, is considered the first esolang in history: its goal was specifically intended to be different from traditional languages and so for example a level of politeness was introduced -- if there weren't enough PLEASE labels in the source code, the compiler wouldn't compile the program.
