INTERCAL
INTERCAL, short for Compiler Language With No Pronounceable Acronym, was created in 1972 by Don Woods and James Lyon at Princeton University. INTERCAL is an esoteric programming language designed as a parody of contemporary languages like Fortran and COBOL, intentionally difficult to read and write. It is primarily used for educational purposes, programming humor, and exploring the limits of language design.
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.
