Brainfuck operates on a simple memory tape and a pointer, performing operations using only eight commands.

It is Turing-complete, meaning it can theoretically compute anything a conventional programming language can, despite its minimal syntax.

The language is intentionally difficult to read and write, making it more of a mental exercise and educational tool than a practical programming language.

Increment/decrement memory cell value (+/-)

Move pointer left or right (< >)

Input/output operations (, .)

Loop constructs using [ ]

No native variables, functions, or data types

Memory tape: linear array of cells storing numeric values

Pointer: tracks the current cell in the tape

Commands: +, -, <, >, [, ], ., ,

Loops: [ ] execute as long as the current cell is non-zero

Input/output: , reads a character; . writes a character

scripts/ - Brainfuck source files

examples/ - classic Brainfuck programs (Hello World, FizzBuzz)

tests/ - tape state or output verification

Brainfuck vs Python: Brainfuck is minimal and esoteric; Python is practical and high-level

Brainfuck vs C: Brainfuck is pointer-tape based; C provides structured low-level operations

Brainfuck vs Assembly: Both are low-level in spirit, but Brainfuck is extreme minimalism

Brainfuck vs JavaScript: Brainfuck is for learning/puzzles; JavaScript is production-ready

Brainfuck vs Malbolge: Both esoteric; Brainfuck slightly easier to reason about
