# Brainfuck
Brainfuck is an extremely simple, [minimalist](minimalism.md) untyped [esoteric programming language](esoland.md); simple by its specification (consisting only of 8 commands) but very hard to program in (it is so called [Turing tarpit](turing_tarpit.md)). It works similarly to a pure [Turing machine](turing_machine.md). In a way it is kind of [beautiful](beauty.md) by its [simplicity](minimalism.md), it is very easy to write your own brainfuck [interpreter](interpreter.md) (or [compiler](compiler.md)) -- in fact the Brainfuck author's goal was to make a language for which the smallest compiler could be made.
Brainfuck is an extremely simple, [minimalist](minimalism.md) untyped [esoteric programming language](esolang.md); simple by its specification (consisting only of 8 commands) but very hard to program in (it is so called [Turing tarpit](turing_tarpit.md)). It works similarly to a pure [Turing machine](turing_machine.md).

There exist **[self-hosted](self_hosting.md) Brainfuck interpreters and compilers** (i.e. themselves written in Brainfuck) which is pretty fucked up. The smallest one is probably the one called [dbfi](dbfi.md) which has only slightly above 400 characters, that's incredible!!! (Esolang wiki states that it's one of the smallest self interpreters among imperative languages). Of course, **Brainfuck [quines](quine.md)** (programs printing their own source code) also exist, but it's not easy to make them -- one example found on the web was a little over 2100 characters long.
