Brainfuck has one of the smallest compilers among all other software languages. That’s why it’s known as one of the smallest software languages in the world(for now :).
- [ - ] is the smallest program written in this language.
- ASCII Table is used for the character mapping.
Basically it has 8 program instructions as the following:
