What is "brainfuck"

n. A minimalist esoteric programming language, created for amusement, in which every basic machine instruction is represented by a single character.

Brainfuck is an esoteric programming language created in 1993 by Urban Müller, and notable for its extreme minimalism.

The language consists of only eight simple commands and an instruction pointer. While it is fully Turing-complete, it is not intended for practical use, but to challenge and amuse programmers.

The language's name is a reference to the slang term brainfuck, which refers to things so complicated or unusual that they exceed the limits of one's understanding.
