Befunge
Befunge, short for Befunge-93, was created in 1993 by Chris Pressey. Befunge is an esoteric, two-dimensional, stack-based programming language where code is arranged on a grid and the instruction pointer can move in multiple directions. It is primarily used for experimentation, education, and exploring unconventional programming paradigms. Developers can access Befunge via implementations such as the official Befunge Interpreter, which provides executables and source code for Windows, macOS, and Linux.
Whitespace
Whitespace, short for Whitespace Programming Language, is an esoteric programming language in which only spaces, tabs, and linefeeds have syntactic meaning. It is primarily used for experimental purposes, puzzles, and educational exploration of language design, rather than conventional application development. Developers can write Whitespace programs using any plain text editor and execute them with interpreters available at official repositories such as the Whitespace GitHub project.
