Programming Languages You've Never Heard Of

An exploration of unusual esoteric programming languages including Brainfuck (a minimalist language with only 8 commands and a 240-byte compiler), Malbolge (designed to be impossibly difficult with self-encrypting code and ternary logic), INTERCAL (a 1972 parody language requiring polite syntax), Piet (where code is abstract art using colored pixels), and Chef (programs written as cooking recipes). These languages demonstrate extreme design choices and theoretical concepts like Turing completeness, though they're intentionally impractical for real-world use.
