An esoteric programming language, or “esolang”, is a computer programming language

intended to entertain or confuse, to be a joke or to explore new concepts.

Esolangs may be minimalistic or, conversely, bloated.

Often an esolang has features that made it harder to use on purpose.

Esolangs are mostly not designed for serious use, unlike mainstream languages.

Spleeshmicannon / NotBrainFuck

My own version of BrainFuck. It adds 8 new symbols. These are all to make the language easier to use for beginners. Hence coining the name NotBrainFuck, since it goes against many of the original languages principals. I'm a first year CS major so I am happy to accept and learn from any criticisms.
