Esolangs, short for "esoteric programming languages," are programming languages created primarily for experimentation, humor, or artistic expression rather than practical use. They often challenge conventional programming paradigms and can be intentionally difficult to understand or use. Examples include Brainfuck, which uses a minimalistic set of commands, and Whitespace, where only spaces, tabs, and newlines are significant. These languages are often developed by enthusiasts who enjoy pushing the boundaries of what programming can be. While they may not be suitable for real-world applications, esolangs can provide insight into programming concepts and inspire creativity among developers and hobbyists alike.
