Cat

The Cat programming language is a functional stack-based programming language, with an optional static type-system. Think Forth meets Haskell, inspired by the Joy programming language. The Cat language is maintained by the language designer Christopher Diggins.

Originally created in 2008 using the C# programming language targeting only the Windows operating system, Cat has been re-written in TypeScript and translated to ES5 compliant JavaScript for use on other platforms.
